Struct rp2040_pac2::pio::regs::SmShiftctrl

#[repr(transparent)]pub struct SmShiftctrl(pub u32);

Control behaviour of the input/output shift registers for state machine 1

Implementations

impl SmShiftctrl

pub const fn fjoin_rx(&self) -> bool

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.

pub fn set_fjoin_rx(&mut self, val: bool)

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.

pub const fn fjoin_tx(&self) -> bool

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.

pub fn set_fjoin_tx(&mut self, val: bool)

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.

pub const fn pull_thresh(&self) -> u8

Number of bits shifted out of TXSR before autopull or conditional pull. Write 0 for value of 32.

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

Number of bits shifted out of TXSR before autopull or conditional pull. Write 0 for value of 32.

pub const fn push_thresh(&self) -> u8

Number of bits shifted into RXSR before autopush or conditional push. Write 0 for value of 32.

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

Number of bits shifted into RXSR before autopush or conditional push. Write 0 for value of 32.

pub const fn out_shiftdir(&self) -> bool

1 = shift out of output shift register to right. 0 = to left.

pub fn set_out_shiftdir(&mut self, val: bool)

1 = shift out of output shift register to right. 0 = to left.

pub const fn in_shiftdir(&self) -> bool

1 = shift input shift register to right (data enters from left). 0 = to left.

pub fn set_in_shiftdir(&mut self, val: bool)

1 = shift input shift register to right (data enters from left). 0 = to left.

pub const fn autopull(&self) -> bool

Pull automatically when the output shift register is emptied

pub fn set_autopull(&mut self, val: bool)

Pull automatically when the output shift register is emptied

pub const fn autopush(&self) -> bool

Push automatically when the input shift register is filled

pub fn set_autopush(&mut self, val: bool)

Push automatically when the input shift register is filled
