Implementations§

source §

impl SniffCtrl

source

pub const fn en(&self) -> bool

Enable sniffer

source

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

Enable sniffer

source

pub const fn dmach(&self) -> u8

DMA channel for Sniffer to observe

source

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

DMA channel for Sniffer to observe

source

pub const fn calc(&self) -> Calc

source

pub fn set_calc(&mut self, val: Calc)

source

pub const fn bswap(&self) -> bool

Locally perform a byte reverse on the sniffed data, before feeding into checksum. Note that the sniff hardware is downstream of the DMA channel byteswap performed in the read master: if channel CTRL_BSWAP and SNIFF_CTRL_BSWAP are both enabled, their effects cancel from the sniffer’s point of view.

source

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

Locally perform a byte reverse on the sniffed data, before feeding into checksum. Note that the sniff hardware is downstream of the DMA channel byteswap performed in the read master: if channel CTRL_BSWAP and SNIFF_CTRL_BSWAP are both enabled, their effects cancel from the sniffer’s point of view.

source

pub const fn out_rev(&self) -> bool

If set, the result appears bit-reversed when read. This does not affect the way the checksum is calculated; the result is transformed on-the-fly between the result register and the bus.

source

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

If set, the result appears bit-reversed when read. This does not affect the way the checksum is calculated; the result is transformed on-the-fly between the result register and the bus.

source

pub const fn out_inv(&self) -> bool

If set, the result appears inverted (bitwise complement) when read. This does not affect the way the checksum is calculated; the result is transformed on-the-fly between the result register and the bus.

source

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

If set, the result appears inverted (bitwise complement) when read. This does not affect the way the checksum is calculated; the result is transformed on-the-fly between the result register and the bus.
