This field is cleared when SCR.TXUR is written to one
Bit i of this field is set when a transmit underrun error occurred in channel i (i=0 for first channel of the frame)
This field is cleared when SCR.RXOR is written to one
Bit i of this field is set when a receive overrun error occurred in channel i (i=0 for first channel of the frame)
This bit is cleared when the corresponding bit in SCR is written to one
This bit is set when an underrun error occurs on the THR register or when the corresponding bit in SSR is written to one
This bit is cleared when data is written to THR
This bit is set when the THR register is empty and can be written with new data to be transmitted
This bit is cleared when the Transmitter is effectively disabled, following a CR.TXDIS or CR.SWRST request
This bit is set when the Transmitter is effectively enabled, following a CR.TXEN request
This bit is cleared when the corresponding bit in SCR is written to one
This bit is set when an overrun error occurs on the RHR register or when the corresponding bit in SSR is written to one
This bit is cleared when the RHR register is read
This bit is set when received data is present in the RHR register
This bit is cleared when the Receiver is effectively disabled, following a CR.RXDIS or CR.SWRST request
This bit is set when the Receiver is effectively enabled, following a CR.RXEN request
