Read only
This 8-bit read only register reflects the current status of UART.
Description
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, that is, no more data is present in the shift register.
Cleared automatically by writing to COMTX.
COMTX empty status bit.
Set automatically if COMTX is empty. COMTX can be written to as soon as the THRE bit is set, but the
previous data might not have been transmitted yet and may still be present in the shift register.
Cleared automatically by writing to COMTX.
Break indicator.
Set when SIN is held low for more than the maximum word length.
Cleared automatically.
Framing error.
Set when the stop bit is invalid.
Cleared automatically.
Parity error.
Set when a parity error occurs.
Cleared automatically.
Overrun error.
Set automatically if data is overwritten before being read.
Cleared automatically.
Data ready.
Set automatically when COMRX is full.
Cleared by reading COMRX.
