impl W
sourcepub fn frl(&mut self) -> FRL_W<'_, 0>
pub fn frl(&mut self) -> FRL_W<'_, 0>
Bits 0:7 - Frame length. These bits are set and cleared by software. They define the audio frame length expressed in number of SCK clock cycles: the number of bits in the frame is equal to FRL[7:0]
-
- The minimum number of bits to transfer in an audio frame must be equal to 8, otherwise the audio block will behaves in an unexpected way. This is the case when the data size is 8 bits and only one slot 0 is defined in NBSLOT[4:0] of SAI_xSLOTR register (NBSLOT[3:0] = 0000). In master mode, if the master clock (available on MCLK_x pin) is used, the frame length should be aligned with a number equal to a power of 2, ranging from 8 to 256. When the master clock is not used (NODIV = 1), it is recommended to program the frame length to an value ranging from 8 to 256. These bits are meaningless and are not used in AC97 or SPDIF audio block configuration.
sourcepub fn fsall(&mut self) -> FSALL_W<'_, 8>
pub fn fsall(&mut self) -> FSALL_W<'_, 8>
Bits 8:14 - Frame synchronization active level length. These bits are set and cleared by software. They specify the length in number of bit clock (SCK) + 1 (FSALL[6:0]
-
- of the active level of the FS signal in the audio frame These bits are meaningless and are not used in AC97 or SPDIF audio block configuration. They must be configured when the audio block is disabled.
sourcepub fn fsdef(&mut self) -> FSDEF_W<'_, 16>
pub fn fsdef(&mut self) -> FSDEF_W<'_, 16>
Bit 16 - Frame synchronization definition. This bit is set and cleared by software. When the bit is set, the number of slots defined in the SAI_xSLOTR register has to be even. It means that half of this number of slots will be dedicated to the left channel and the other slots for the right channel (e.g: this bit has to be set for I2S or MSB/LSB-justified protocols…). This bit is meaningless and is not used in AC97 or SPDIF audio block configuration. It must be configured when the audio block is disabled.
sourcepub fn fspol(&mut self) -> FSPOL_W<'_, 17>
pub fn fspol(&mut self) -> FSPOL_W<'_, 17>
Bit 17 - Frame synchronization polarity. This bit is set and cleared by software. It is used to configure the level of the start of frame on the FS signal. It is meaningless and is not used in AC97 or SPDIF audio block configuration. This bit must be configured when the audio block is disabled.
