Struct stm32h7::stm32h743v::fmc::sdcmr::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 mode(&mut self) -> _MODEW

Bits 0:2 - Command mode These bits define the command issued to the SDRAM device. Note: When a command is issued, at least one Command Target Bank bit ( CTB1 or CTB2) must be set otherwise the command will be ignored. Note: If two SDRAM banks are used, the Auto-refresh and PALL command must be issued simultaneously to the two devices with CTB1 and CTB2 bits set otherwise the command will be ignored. Note: If only one SDRAM bank is used and a command is issued with its associated CTB bit set, the other CTB bit of the unused bank must be kept to 0.

pub fn ctb2(&mut self) -> _CTB2W

Bit 3 - Command Target Bank 2 This bit indicates whether the command will be issued to SDRAM Bank 2 or not.

pub fn ctb1(&mut self) -> _CTB1W

Bit 4 - Command Target Bank 1 This bit indicates whether the command will be issued to SDRAM Bank 1 or not.

pub fn nrfs(&mut self) -> _NRFSW

Bits 5:8 - Number of Auto-refresh These bits define the number of consecutive Auto-refresh commands issued when MODE = 011. ....

pub fn mrd(&mut self) -> _MRDW

Bits 9:22 - Mode Register definition This 14-bit field defines the SDRAM Mode Register content. The Mode Register is programmed using the Load Mode Register command. The MRD[13:0] bits are also used to program the extended mode register for mobile SDRAM.
