Struct lpc81x_pac::i2c::stat::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 mstpending(&self) -> MSTPENDINGR

Bit 0 - Master Pending. Indicates whether the Master function needs software service. This flag will cause an interrupt when set if enabled via the INTENSET register. The MSTPENDING flag is automatically cleared when a 1 is written to the MSTCONTINUE bit in the MSTCTL register.

pub fn mststate(&self) -> MSTSTATER

Bits 1:3 - Master State code. Each value of this field indicates a specific required service for the Master function. All other values are reserved.

pub fn mstarbloss(&self) -> MSTARBLOSSR

Bit 4 - Master Arbitration Loss flag. This flag can be cleared by software writing a 1 to this bit. It is also cleared automatically a 1 is written to MSTCONTINUE.

pub fn mstststperr(&self) -> MSTSTSTPERRR

Bit 6 - Master Start/Stop Error flag. This flag can be cleared by software writing a 1 to this bit. It is also cleared automatically a 1 is written to MstContinue.

pub fn slvpending(&self) -> SLVPENDINGR

Bit 8 - Slave Pending. Indicates whether the Slave function needs software service. This flag will cause an interrupt when set if enabled via INTENSET. The SLVPENDING flag is read-only and is automatically cleared when a 1 is written to the SLVCONTINUE bit in the MSTCTL register.

pub fn slvstate(&self) -> SLVSTATER

Bits 9:10 - Slave State code. Each value of this field indicates a specific required service for the Slave function. All other values are reserved.

pub fn slvnotstr(&self) -> SLVNOTSTRR

Bit 11 - Slave Not Stretching. Indicates when the slave function is stretching the I2C clock. This is needed in order to gracefully invoke Deep Sleep or Power-down modes during slave operation. This read-only flag reflects the slave function status in real time.

pub fn slvidx(&self) -> SLVIDXR

Bits 12:13 - Slave address match Index. This field is valid when the I2C slave function has been selected by receiving an address that matches one of the slave addresses defined by any enabled slave address registers, and provides an identification of the address that was matched. It is possible that more than one address could be matched, but only one match can be reported here.

pub fn slvsel(&self) -> SLVSELR

Bit 14 - Slave selected flag. SLVSEL is set after an address match when software tells the Slave function to acknowledge the address. It is cleared when another address cycle presents an address that does not match an enabled address on the Slave function, when slave software decides to Nack a matched address, or when there is a Stop detected on the bus. SLVSEL is not cleared if software Nacks data.

pub fn slvdesel(&self) -> SLVDESELR

Bit 15 - Slave Deselected flag. This flag will cause an interrupt when set if enabled via INTENSET. This flag can be cleared by writing a 1 to this bit.

pub fn monrdy(&self) -> MONRDYR

Bit 16 - Monitor Ready. This flag is cleared when the MONRXDAT register is read.

pub fn monov(&self) -> MONOVR

Bit 17 - Monitor Overflow flag.

pub fn monactive(&self) -> MONACTIVER

Bit 18 - Monitor Active flag. This flag indicates when the Monitor function considers the I2C bus to be active. Active is defined here as when some Master is on the bus: a bus Start has occurred more recently than a bus Stop.

pub fn monidle(&self) -> MONIDLER

Bit 19 - Monitor Idle flag. This flag is set when the Monitor function sees the I2C bus change from active to inactive. This can be used by software to decide when to process data accumulated by the Monitor function. This flag will cause an interrupt when set if enabled via the INTENSET register . The flag can be cleared by writing a 1 to this bit.

pub fn eventtimeout(&self) -> EVENTTIMEOUTR

Bit 24 - Event Time-out Interrupt flag. Indicates when the time between events has been longer than the time specified by the TIMEOUT register. Events include Start, Stop, and clock edges. The case of SCL remaining low longer than TIMEOUT is not reported by this flag, it is reported in by the SCL Time-out flag. The flag is cleared by writing a 1 to this bit.

pub fn scltimeout(&self) -> SCLTIMEOUTR

Bit 25 - SCL Time-out Interrupt flag. Indicates when SCL has remained low longer than the time specific by the TIMEOUT register. The flag is cleared by writing a 1 to this bit.
