Implementations§
source§impl R
impl R
sourcepub fn autopush(&self) -> AUTOPUSH_R
pub fn autopush(&self) -> AUTOPUSH_R
Bit 16 - Push automatically when the input shift register is filled, i.e. on an IN instruction which causes the input shift counter to reach or exceed PUSH_THRESH.
sourcepub fn autopull(&self) -> AUTOPULL_R
pub fn autopull(&self) -> AUTOPULL_R
Bit 17 - Pull automatically when the output shift register is emptied, i.e. on or following an OUT instruction which causes the output shift counter to reach or exceed PULL_THRESH.
sourcepub fn in_shiftdir(&self) -> IN_SHIFTDIR_R
pub fn in_shiftdir(&self) -> IN_SHIFTDIR_R
Bit 18 - 1 = shift input shift register to right (data enters from left). 0 = to left.
sourcepub fn out_shiftdir(&self) -> OUT_SHIFTDIR_R
pub fn out_shiftdir(&self) -> OUT_SHIFTDIR_R
Bit 19 - 1 = shift out of output shift register to right. 0 = to left.
sourcepub fn push_thresh(&self) -> PUSH_THRESH_R
pub fn push_thresh(&self) -> PUSH_THRESH_R
Bits 20:24 - Number of bits shifted into ISR before autopush, or conditional push (PUSH IFFULL), will take place.
Write 0 for value of 32.
sourcepub fn pull_thresh(&self) -> PULL_THRESH_R
pub fn pull_thresh(&self) -> PULL_THRESH_R
Bits 25:29 - Number of bits shifted out of OSR before autopull, or conditional pull (PULL IFEMPTY), will take place.
Write 0 for value of 32.
sourcepub fn fjoin_tx(&self) -> FJOIN_TX_R
pub fn fjoin_tx(&self) -> FJOIN_TX_R
Bit 30 - When 1, TX FIFO steals the RX FIFO’s storage, and becomes twice as deep.
RX FIFO is disabled as a result (always reads as both full and empty).
FIFOs are flushed when this bit is changed.
sourcepub fn fjoin_rx(&self) -> FJOIN_RX_R
pub fn fjoin_rx(&self) -> FJOIN_RX_R
Bit 31 - When 1, RX FIFO steals the TX FIFO’s storage, and becomes twice as deep.
TX FIFO is disabled as a result (always reads as both full and empty).
FIFOs are flushed when this bit is changed.
