Structs
Deep power-down control register. Also includes bits for general purpose storage.
Field GPDATA
reader - Data retained during Deep power-down mode.
Field GPDATA
writer - Data retained during Deep power-down mode.
Field LPOSCDPDEN
reader - causes the low-power oscillator to remain running during Deep power-down mode provided that bit 2 in this register is set as well. You must set this bit for the self wake-up timer to be able to wake up the part from Deep power-down mode. Remark: Do not set this bit unless you use the self wake-up timer with the low-power oscillator clock source to wake up from Deep power-down mode.

writer - causes the low-power oscillator to remain running during Deep power-down mode provided that bit 2 in this register is set as well. You must set this bit for the self wake-up timer to be able to wake up the part from Deep power-down mode. Remark: Do not set this bit unless you use the self wake-up timer with the low-power oscillator clock source to wake up from Deep power-down mode.
Field LPOSCEN
reader - Enable the low-power oscillator for use with the 10 kHz self wake-up timer clock. You must set this bit if the CLKSEL bit in the self wake-up timer CTRL bit is set. Do not enable the low-power oscillator if the self wake-up timer is clocked by the divided IRC or the external clock input.
Field LPOSCEN
writer - Enable the low-power oscillator for use with the 10 kHz self wake-up timer clock. You must set this bit if the CLKSEL bit in the self wake-up timer CTRL bit is set. Do not enable the low-power oscillator if the self wake-up timer is clocked by the divided IRC or the external clock input.
Register DPDCTRL
reader
Field RESETHYS
reader - RESET pin hysteresis enable.
Field RESETHYS
writer - RESET pin hysteresis enable.
Field RESET_DISABLE
reader - RESET pin disable. Setting this bit disables the reset wake-up function, so the pin can be used for other purposes. Remark: Setting this bit is not necessary if deep power-down mode is not used.
Field RESET_DISABLE
writer - RESET pin disable. Setting this bit disables the reset wake-up function, so the pin can be used for other purposes. Remark: Setting this bit is not necessary if deep power-down mode is not used.
Register DPDCTRL
writer
Field WAKECLKPAD_DISABLE
reader - Disable the external clock input for the self-wake-up timer. Setting this bit enables the self-wake-up timer clock pin WKTCLKLIN. To minimize power consumption, especially in deep power-down mode, disable this clock input when not using the external clock option for the self-wake-up timer.
Field WAKECLKPAD_DISABLE
writer - Disable the external clock input for the self-wake-up timer. Setting this bit enables the self-wake-up timer clock pin WKTCLKLIN. To minimize power consumption, especially in deep power-down mode, disable this clock input when not using the external clock option for the self-wake-up timer.
Field WAKEPAD_DISABLE
reader - WAKEUP pin disable. Setting this bit disables the wake-up pin, so it can be used for other purposes. Remark: Never set this bit if you intend to use a pin to wake up the part from Deep power-down mode. You can only disable the wake-up pin if the self wake-up timer is enabled and configured. Remark: Setting this bit is not necessary if Deep power-down mode is not used.

Field WAKEUPCLKHYS
reader - External clock input for the self wake-up timer WKTCLKIN hysteresis enable.
Field WAKEUPCLKHYS
writer - External clock input for the self wake-up timer WKTCLKIN hysteresis enable.
Field WAKEUPHYS
reader - WAKEUP pin hysteresis enable
Field WAKEUPHYS
writer - WAKEUP pin hysteresis enable
