Reserved
COMTX and shift register empty status bit
Set automatically if COMTX and the shift register are empty. This bit indicates that the data has been
transmitted, i.e. is no more present in the shift register.
Cleared automatically when writing to COMTX
COMTX empty status bit.
Set automatically if COMTX is empty. COMTX can be written is soon as this bit gets set, the previous data
might not have been transmitted yet and still be present in the shift register.
Cleared automatically when writing to COMTX
Break Indicator
Set when SIN is held low for more than the maximum word length
Cleared automatically
Framing error
Set when invalid stop bit
Cleared automatically
Parity error
Set when a parity error occurs
Cleared automatically
Overrun error
Set automatically if data are overwrite before been read
Cleared automatically
Data ready
Set automatically when COMRX is full
