impl Cfgr1

pub const fn sitp(&self) -> u8

pub const fn spicksel(&self) -> u8

SPI clock select for channel y 2: clock coming from internal CKOUT - sampling point on each second CKOUT falling edge. For connection to external sigma-delta modulator which divides its clock input (from CKOUT) by 2 to generate its output serial communication clock (and this output clock change is active on each clock input rising edge). 3: clock coming from internal CKOUT output - sampling point on each second CKOUT rising edge. For connection to external sigma-delta modulator which divides its clock input (from CKOUT) by 2 to generate its output serial communication clock (and this output clock change is active on each clock input falling edge). This value can be modified only when CHEN=0 (in DFSDM_CHyCFGR1 register).

pub const fn datmpx(&self) -> u8

Input data multiplexer for channel y 2: Data to channel y are taken from internal DFSDM_CHyDATINR register by direct CPU/DMA write. There can be written one or two 16-bit data samples according DATPACK[1:0] bit field setting. 3: Reserved This value can be modified only when CHEN=0 (in DFSDM_CHyCFGR1 register).

pub const fn datpack(&self) -> u8

Data packing mode in DFSDM_CHyDATINR register. first sample in INDAT0[15:0] (assigned to channel y) second sample INDAT1[15:0] (assigned to channel y) To empty DFSDM_CHyDATINR register, two samples must be read by the digital filter from channel y (INDAT0[15:0] part is read as first sample and then INDAT1[15:0] part is read as next sample). 2: Dual: input data in DFSDM_CHyDATINR register are stored as two samples: first sample INDAT0[15:0] (assigned to channel y) second sample INDAT1[15:0] (assigned to channel y+1) To empty DFSDM_CHyDATINR register first sample must be read by the digital filter from channel y and second sample must be read by another digital filter from channel y+1. Dual mode is available only on even channel numbers (y = 0, 2, 4, 6), for odd channel numbers (y = 1, 3, 5, 7) DFSDM_CHyDATINR is write protected. If an even channel is set to dual mode then the following odd channel must be set into standard mode (DATPACK[1:0]=0) for correct cooperation with even channel. 3: Reserved This value can be modified only when CHEN=0 (in DFSDM_CHyCFGR1 register).

pub const fn ckoutdiv(&self) -> u8

Output serial clock divider 256 (Divider = CKOUTDIV+1). CKOUTDIV also defines the threshold for a clock absence detection. This value can only be modified when DFSDMEN=0 (in DFSDM_CH0CFGR1 register). If DFSDMEN=0 (in DFSDM_CH0CFGR1 register) then CKOUT signal is set to low state (setting is performed one DFSDM clock cycle after DFSDMEN=0). Note: CKOUTDIV is present only in DFSDM_CH0CFGR1 register (channel y=0) 1- 255: Defines the division of system clock for the serial clock output for CKOUT signal in range 2 - 256.

Output serial clock divider 256 (Divider = CKOUTDIV+1). CKOUTDIV also defines the threshold for a clock absence detection. This value can only be modified when DFSDMEN=0 (in DFSDM_CH0CFGR1 register). If DFSDMEN=0 (in DFSDM_CH0CFGR1 register) then CKOUT signal is set to low state (setting is performed one DFSDM clock cycle after DFSDMEN=0).

pub const fn ckoutsrc(&self) -> bool

Output serial clock source selection This value can be modified only when DFSDMEN=0 (in DFSDM_CH0CFGR1 register). Note: CKOUTSRC is present only in DFSDM_CH0CFGR1 register (channel y=0).

pub const fn dfsdmen(&self) -> bool

Global enable for DFSDM interface If DFSDM interface is enabled, then it is started to operate according to enabled y channels and enabled x filters settings (CHEN bit in DFSDM_CHyCFGR1 and DFEN bit in DFSDM_FLTxCR1). Data cleared by setting DFSDMEN=0: all registers DFSDM_FLTxISR are set to reset state (x = 0..7) all registers DFSDM_FLTxAWSR are set to reset state (x = 0..7) Note: DFSDMEN is present only in DFSDM_CH0CFGR1 register (channel y=0).

pub const fn set_dfsdmen(&mut self, val: bool)

Global enable for DFSDM interface If DFSDM interface is enabled, then it is started to operate according to enabled y channels and enabled x filters settings (CHEN bit in DFSDM_CHyCFGR1 and DFEN bit in DFSDM_FLTxCR1). Data cleared by setting DFSDMEN=0: all registers DFSDM_FLTxISR are set to reset state (x = 0..7) all registers DFSDM_FLTxAWSR are set to reset state (x = 0..7) Note: DFSDMEN is present only in DFSDM_CH0CFGR1 register (channel y=0).
