Struct rp_pac::i2c::regs::IcSlvDataNackOnly

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

Generate Slave Data NACK Register The register is used to generate a NACK for the data part of a transfer when DW_apb_i2c is acting as a slave-receiver. This register only exists when the IC_SLV_DATA_NACK_ONLY parameter is set to 1. When this parameter disabled, this register does not exist and writing to the register’s address has no effect. A write can occur on this register if both of the following conditions are met: - DW_apb_i2c is disabled (IC_ENABLE[0] = 0) - Slave part is inactive (IC_STATUS[6] = 0) Note: The IC_STATUS[6] is a register read-back location for the internal slv_activity signal; the user should poll this before writing the ic_slv_data_nack_only bit.

Implementations

impl IcSlvDataNackOnly

pub const fn nack(&self) -> bool

Generate NACK. This NACK generation only occurs when DW_apb_i2c is a slave-receiver. If this register is set to a value of 1, it can only generate a NACK after a data byte is received; hence, the data transfer is aborted and the data received is not pushed to the receive buffer. When the register is set to a value of 0, it generates NACK/ACK, depending on normal criteria. - 1: generate NACK after data byte received - 0: generate NACK/ACK normally Reset value: 0x0

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

Generate NACK. This NACK generation only occurs when DW_apb_i2c is a slave-receiver. If this register is set to a value of 1, it can only generate a NACK after a data byte is received; hence, the data transfer is aborted and the data received is not pushed to the receive buffer. When the register is set to a value of 0, it generates NACK/ACK, depending on normal criteria. - 1: generate NACK after data byte received - 0: generate NACK/ACK normally Reset value: 0x0

Trait Implementations

impl Clone for IcSlvDataNackOnly

fn clone(&self) -> IcSlvDataNackOnly

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for IcSlvDataNackOnly

fn default() -> IcSlvDataNackOnly

Returns the “default value” for a type.

impl PartialEq for IcSlvDataNackOnly

fn eq(&self, other: &IcSlvDataNackOnly) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
