impl Dcr1
pub const fn ckmode(&self) -> bool
pub const fn ckmode(&self) -> bool
Mode 0/Mode 3 This bit indicates the level taken by the CLK between commands (when nCS = 1).
pub fn set_ckmode(&mut self, val: bool)
pub fn set_ckmode(&mut self, val: bool)
Mode 0/Mode 3 This bit indicates the level taken by the CLK between commands (when nCS = 1).
pub fn set_dlybyp(&mut self, val: bool)
pub fn set_dlybyp(&mut self, val: bool)
Delay block bypass.
pub const fn csht(&self) -> u8
pub const fn csht(&self) -> u8
Chip-select high time CSHT├é┬á+├é┬á1 defines the minimum number of CLK cycles where the chip-select (nCS) must remain high between commands issued to the external device. … 63: nCS stays high for at least 64 cycles between external device commands. Note: When the extended CSHT timeout feature is not supported, CSHT[5:3] are reserved and the number of cycles is limited to eight (refer to implementation).

pub const fn devsize(&self) -> u8
pub const fn devsize(&self) -> u8
Device size This field defines the size of the external device using the following formula: Number of bytes in device = 2[DEVSIZE+1]. DEVSIZE+1 is effectively the number of address bits required to address the external device. The device capacity can be up to 4 Gbytes (addressed using 32-bits) in Indirect mode, but the addressable space in Memory-mapped mode is limited to 256 Mbytes. In Regular-command mode, if DMM = 1, DEVSIZE[4:0] indicates the total capacity of the two devices together.

pub const fn mtyp(&self) -> u8
pub const fn mtyp(&self) -> u8
Memory type This bit indicates the type of memory to be supported. Note: In this mode, DQS signal polarity is inverted with respect to the memory clock signal. This is the default value and care must be taken to change MTYP[2:0] for memories different from Micron. Others: Reserved.
