Struct lpc55s6x_pac::i2c0::mstctl::R

pub struct R { /* fields omitted */ }

Value read from the register

Methods

impl R

pub fn bits(&self) -> u32

Value of the register as raw bits

pub fn mststart(&self) -> MSTSTARTR

Bit 1 - Master Start control. This bit is write-only.

pub fn mststop(&self) -> MSTSTOPR

Bit 2 - Master Stop control. This bit is write-only.

pub fn mstdma(&self) -> MSTDMAR

Bit 3 - Master DMA enable. Data operations of the I2C can be performed with DMA. Protocol type operations such as Start, address, Stop, and address match must always be done with software, typically via an interrupt. Address acknowledgement must also be done by software except when the I2C is configured to be HSCAPABLE (and address acknowledgement is handled entirely by hardware) or when Automatic Operation is enabled. When a DMA data transfer is complete, MSTDMA must be cleared prior to beginning the next operation, typically a Start or Stop.This bit is read/write.
