Struct stm32g0::stm32g0c1::hdmi_cec::cec_cr::R

pub struct R(_);

Register CEC_CR reader

Implementations

impl R

pub fn cecen(&self) -> CECEN_R

Bit 0 - CEC enable The CECEN bit is set and cleared by software. CECEN = 1 starts message reception and enables the TXSOM control. CECEN = 0 disables the CEC peripheral, clears all bits of CEC_CR register and aborts any on-going reception or transmission.

pub fn txsom(&self) -> TXSOM_R

Bit 1 - Tx start of message TXSOM is set by software to command transmission of the first byte of a CEC message. If the CEC message consists of only one byte, TXEOM must be set before of TXSOM. Start-bit is effectively started on the CEC line after SFT is counted. If TXSOM is set while a message reception is ongoing, transmission starts after the end of reception. TXSOM is cleared by hardware after the last byte of the message is sent with a positive acknowledge (TXEND = 1), in case of transmission underrun (TXUDR = 1), negative acknowledge (TXACKE = 1), and transmission error (TXERR = 1). It is also cleared by CECEN = 0. It is not cleared and transmission is automatically retried in case of arbitration lost (ARBLST = 1). TXSOM can be also used as a status bit informing application whether any transmission request is pending or under execution. The application can abort a transmission request at any time by clearing the CECEN bit. Note: TXSOM must be set when CECEN = 1. TXSOM must be set when transmission data is available into TXDR. HEADER first four bits containing own peripheral address are taken from TXDR[7:4], not from CEC_CFGR.OAR that is used only for reception.

pub fn txeom(&self) -> TXEOM_R

Bit 2 - Tx end of message The TXEOM bit is set by software to command transmission of the last byte of a CEC message. TXEOM is cleared by hardware at the same time and under the same conditions as for TXSOM. Note: TXEOM must be set when CECEN = 1. TXEOM must be set before writing transmission data to TXDR. If TXEOM is set when TXSOM = 0, transmitted message consists of 1 byte (HEADER) only (PING message).
