bit 4
RIDLE: Receiver Idle bit (Read-Only)
1
= Receiver is Idle
0
= Receiver is active
bit 3
PERR: Parity Error Status bit (Read-Only)
1
= Parity error has been detected for the current character (character at the top of the receive FIFO)
0
= Parity error has not been detected
bit 2
FERR: Framing Error Status bit (Read-Only)
1
= Framing error has been detected for the current character (character at the top of the receive
FIFO)
0
= Framing error has not been detected
bit 1
OERR: Receive Buffer Overrun Error Status bit (Read/Clear-Only)
1
= Receive buffer has overflowed
0
= Receive buffer has not overflowed (clearing a previously set OERR bit (1
→ 0 transition) will reset
the receiver buffer and the RSR to the empty state)
bit 0
URXDA: Receive Buffer Data Available bit (Read-Only)
1
= Receive buffer has data, at least one more character can be read
0
= Receive buffer is empty
