This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when a SMBus PEC error has occurred.
This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when a SMBus timeout has occurred.
This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when a NAK was received from the master during slave transmitter operation.
This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when an overrun has occurred in slave receiver mode. Can only occur if CR.STREN is zero.
This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when an underrun has occurred in slave transmitter mode. Can only occur if CR.STREN is zero.
0: The slave is in slave receiver mode.
1: The slave is in slave transmitter mode.
This bit is cleared when the corresponding bit in SCR is written to one.
This bit is set when transmission is complete. Set after receiving a STOP after being addressed.
0: The slave interface is disabled.
1: The slave interface is enabled.
0: The TX buffer is full and should not be written to.
1: The TX buffer is empty, and can accept new data.
0: No RX data ready in RHR.
