• PARE: Parity Error (Code Label US_PARE)
1 = At least one parity bit has been detected false (or a parity bit high in Multi-drop Mode) since the last “Reset Status Bits”
command.
0 = No parity bit has been detected false (or a parity bit high in Multi-drop Mode) since the last “Reset Status Bits”
command.
• TIMEOUT: Receiver Time-out (Code Label US_TIMEOUT)
0 = There has not been a time-out since the last “Start Time-out” command or the Time-out Register is 0.
1 = There has been a time-out since the last “Start Time-out” command.
• TXEMPTY: Transmitter Empty (Code Label US_TXEMPTY)
0 = There are characters in either US_THR or the Transmit Shift Register or a Break is being transmitted.
1 = There are no characters in US_THR and the Transmit Shift Register and Break is not active.
Equal to zero when the USART is disabled or at reset. Transmitter Enable command (in US_CR) sets this bit to one.

• RXCHR: Received Character
Last character received if RXRDY is set. When number of data bits is less than 8 bits, the bits are right-aligned.
All non-significant bits read zero.
