bit 7-6

URXISEL<1:0>: UARTx Receive Interrupt Mode Selection bits

11 = Interrupt is set on an RSR transfer, making the receive buffer full (i.e., has four data characters)

10 = Interrupt is set on an RSR transfer, making the receive buffer 3/4 full (i.e., has three data characters)

0x = Interrupt is set when any character is received and transferred from the RSR to the receive buffer;

receive buffer has one or more characters

bit 5

ADDEN: Address Character Detect bit (bit 8 of received data = 1)

1 = Address Detect mode is enabled (if 9-bit mode is not selected, this does not take effect)

0 = Address Detect mode is disabled

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 (the 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 (the character at the top of the receive FIFO)

0 = Framing error has not been detected

bit 1

OERR: Receive Buffer Overrun Error Status bit (clear/read-only)

1 = Receive buffer has overflowed

0 = Receive buffer has not overflowed (clearing a previously set OERR bit (‘1’-to-‘0’ transition) will

reset the receive buffer and the RSR to the empty state)

bit 0

URXDA: UARTx 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

UxSTA: UARTx STATUS AND CONTROL REGISTER (CONTINUED)

Note 1:

The value of this bit only affects the transmit properties of the module when the IrDA® encoder is enabled

(IREN = 1).

If UARTEN = 1, the peripheral inputs and outputs must be configured to an available RPn/RPIn pin. For

more information, see Section 11.5 “Peripheral Pin Select (PPS)”.
