Structs

AUTOLIMIT_H_R

Field AUTOLIMIT_H reader - A one in this bit will cause a match on match register 0 to be treated as a de-facto LIMIT condition without the need to define an associated event. As with any LIMIT event, this automatic limit causes the counter to be cleared to zero in unidirectional mode or to change the direction of count in bi-directional mode. Software can write to set or clear this bit at any time. This bit is not used when the UNIFY bit is set.

AUTOLIMIT_H_W

Field AUTOLIMIT_H writer - A one in this bit will cause a match on match register 0 to be treated as a de-facto LIMIT condition without the need to define an associated event. As with any LIMIT event, this automatic limit causes the counter to be cleared to zero in unidirectional mode or to change the direction of count in bi-directional mode. Software can write to set or clear this bit at any time. This bit is not used when the UNIFY bit is set.

AUTOLIMIT_L_R

Field AUTOLIMIT_L reader - A one in this bit causes a match on match register 0 to be treated as a de-facto LIMIT condition without the need to define an associated event. As with any LIMIT event, this automatic limit causes the counter to be cleared to zero in unidirectional mode or to change the direction of count in bi-directional mode. Software can write to set or clear this bit at any time. This bit applies to both the higher and lower registers when the UNIFY bit is set.

AUTOLIMIT_L_W

Field AUTOLIMIT_L writer - A one in this bit causes a match on match register 0 to be treated as a de-facto LIMIT condition without the need to define an associated event. As with any LIMIT event, this automatic limit causes the counter to be cleared to zero in unidirectional mode or to change the direction of count in bi-directional mode. Software can write to set or clear this bit at any time. This bit applies to both the higher and lower registers when the UNIFY bit is set.

CKSEL_R

Field CKSEL reader - SCT clock select. The specific functionality of the designated input/edge is dependent on the CLKMODE bit selection in this register.

CKSEL_W

Field CKSEL writer - SCT clock select. The specific functionality of the designated input/edge is dependent on the CLKMODE bit selection in this register.

CLKMODE_R

Field CLKMODE reader - SCT clock mode

CLKMODE_W

Field CLKMODE writer - SCT clock mode

CONFIG_SPEC

SCT configuration register

INSYNC_R

Field INSYNC reader - Synchronization for input N (bit 9 = input 0, bit 10 = input 1,, bit 12 = input 3); all other bits are reserved. A 1 in one of these bits subjects the corresponding input to synchronization to the SCT clock, before it is used to create an event. If an input is known to already be synchronous to the SCT clock, this bit may be set to 0 for faster input response. (Note: The SCT clock is the system clock for CKMODEs 0-2. It is the selected, asynchronous SCT input clock for CKMODE3). Note that the INSYNC field only affects inputs used for event generation. It does not apply to the clock input specified in the CKSEL field.

INSYNC_W

Field INSYNC writer - Synchronization for input N (bit 9 = input 0, bit 10 = input 1,, bit 12 = input 3); all other bits are reserved. A 1 in one of these bits subjects the corresponding input to synchronization to the SCT clock, before it is used to create an event. If an input is known to already be synchronous to the SCT clock, this bit may be set to 0 for faster input response. (Note: The SCT clock is the system clock for CKMODEs 0-2. It is the selected, asynchronous SCT input clock for CKMODE3). Note that the INSYNC field only affects inputs used for event generation. It does not apply to the clock input specified in the CKSEL field.

NORELOAD_H_R

Field NORELOAD_H reader - A 1 in this bit prevents the higher match registers from being reloaded from their respective reload registers. Setting this bit eliminates the need to write to the reload registers MATCHREL if the match values are fixed. Software can write to set or clear this bit at any time. This bit is not used when the UNIFY bit is set.

NORELOAD_H_W

Field NORELOAD_H writer - A 1 in this bit prevents the higher match registers from being reloaded from their respective reload registers. Setting this bit eliminates the need to write to the reload registers MATCHREL if the match values are fixed. Software can write to set or clear this bit at any time. This bit is not used when the UNIFY bit is set.

NORELOAD_L_R

Field NORELOAD_L reader - A 1 in this bit prevents the lower match registers from being reloaded from their respective reload registers. Setting this bit eliminates the need to write to the reload registers MATCHREL if the match values are fixed. Software can write to set or clear this bit at any time. This bit applies to both the higher and lower registers when the UNIFY bit is set.

NORELOAD_L_W

Field NORELOAD_L writer - A 1 in this bit prevents the lower match registers from being reloaded from their respective reload registers. Setting this bit eliminates the need to write to the reload registers MATCHREL if the match values are fixed. Software can write to set or clear this bit at any time. This bit applies to both the higher and lower registers when the UNIFY bit is set.
