impl Sdcmr

pub const fn mode(&self) -> Mode

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 it’s associated CTB bit set, the other CTB bit of the the unused bank must be kept to 0.

pub fn set_mode(&mut self, val: Mode)

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 it’s associated CTB bit set, the other CTB bit of the the unused bank must be kept to 0.

pub const fn ctb(&self, n: usize) -> bool

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

pub fn set_ctb(&mut self, n: usize, val: bool)

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

pub const fn nrfs(&self) -> u8

Number of Auto-refresh These bits define the number of consecutive Auto-refresh commands issued when MODE = ‘011’. ….

pub fn set_nrfs(&mut self, val: u8)

Number of Auto-refresh These bits define the number of consecutive Auto-refresh commands issued when MODE = ‘011’. ….

pub const fn mrd(&self) -> u16

Mode Register definition This 13-bit field defines the SDRAM Mode Register content. The Mode Register is programmed using the Load Mode Register command.

pub fn set_mrd(&mut self, val: u16)

Mode Register definition This 13-bit field defines the SDRAM Mode Register content. The Mode Register is programmed using the Load Mode Register command.
