Struct stm32h7::stm32h743::mdma::c1tcr::W

pub struct W { /* fields omitted */ }

Value to write to the register

Methods

impl W

pub unsafe fn bits(&mut self, bits: u32) -> &mut Self

Writes raw bits to the register

pub fn sinc(&mut self) -> _SINCW

Bits 0:1 - Source increment mode These bits are set and cleared by software. These bits are protected and can be written only if EN is 0 Note: When source is AHB (SBUS=1), SINC = 00 is forbidden. In Linked List Mode, at the end of a block (single or last block in repeated block transfer mode), this register will be loaded from memory (from address given by current LAR[31:0] + 0x00).

pub fn dinc(&mut self) -> _DINCW

Bits 2:3 - Destination increment mode These bits are set and cleared by software. These bits are protected and can be written only if EN is 0 Note: When destination is AHB (DBUS=1), DINC = 00 is forbidden.

pub fn ssize(&mut self) -> _SSIZEW

Bits 4:5 - Source data size These bits are set and cleared by software. These bits are protected and can be written only if EN is 0 Note: If a value of 11 is programmed for the TCM access/AHB port, a transfer error will occur (TEIF bit set) If SINCOS < SSIZE and SINC ≠ 00, the result will be unpredictable. Note: SSIZE = 11 (double-word) is forbidden when source is TCM/AHB bus (SBUS=1).

pub fn dsize(&mut self) -> _DSIZEW

Bits 6:7 - Destination data size These bits are set and cleared by software. These bits are protected and can be written only if EN is 0. Note: If a value of 11 is programmed for the TCM access/AHB port, a transfer error will occur (TEIF bit set) If DINCOS < DSIZE and DINC ≠ 00, the result will be unpredictable. Note: DSIZE = 11 (double-word) is forbidden when destination is TCM/AHB bus (DBUS=1).

pub fn sincos(&mut self) -> _SINCOSW

Bits 8:9 - source increment offset size

pub fn dincos(&mut self) -> _DINCOSW

Bits 10:11 - Destination increment offset

pub fn sburst(&mut self) -> _SBURSTW

Bits 12:14 - source burst transfer configuration

pub fn dburst(&mut self) -> _DBURSTW

Bits 15:17 - Destination burst transfer configuration

pub fn tlen(&mut self) -> _TLENW

Bits 18:24 - buffer transfer lengh

pub fn pke(&mut self) -> _PKEW

Bit 25 - PacK Enable These bit is set and cleared by software. If the Source Size is smaller than the destination, it will be padded according to the PAM value. If the Source data size is larger than the destination one, it will be truncated. The alignment will be done according to the PAM[0] value. This bit is protected and can be written only if EN is 0

pub fn pam(&mut self) -> _PAMW

Bits 26:27 - Padding/Alignement Mode These bits are set and cleared by software. Case 1: Source data size smaller than destination data size - 3 options are valid. Case 2: Source data size larger than destination data size. The remainder part is discarded. When PKE = 1 or DSIZE=SSIZE, these bits are ignored. These bits are protected and can be written only if EN is 0

pub fn trgm(&mut self) -> _TRGMW

Bits 28:29 - Trigger Mode These bits are set and cleared by software. Note: If TRGM is 11 for the current block, all the values loaded at the end of the current block through the linked list mechanism must keep the same value (TRGM=11) and the same SWRM value, otherwise the result is undefined. These bits are protected and can be written only if EN is 0.

pub fn swrm(&mut self) -> _SWRMW

Bit 30 - SW Request Mode This bit is set and cleared by software. If a HW or SW request is currently active, the bit change will be delayed until the current transfer is completed. If the CxMAR contains a valid address, the CxMDR value will also be written @ CxMAR address. This bit is protected and can be written only if EN is 0.

pub fn bwm(&mut self) -> _BWMW

Bit 31 - Bufferable Write Mode This bit is set and cleared by software. This bit is protected and can be written only if EN is 0. Note: All MDMA destination accesses are non-cacheable.
