PIC32MX1XX/2XX
REGISTER 18-2: UxSTA: UARTx STATUS AND CONTROL REGISTER (CONTINUED)
bit 7-6
URXISEL<1:0>: Receive Interrupt Mode Selection bit
11 = Reserved; do not use
10 = Interrupt flag bit is asserted while receive buffer is 3/4 or more full (i.e., has 6 or more data characters)
01 = Interrupt flag bit is asserted while receive buffer is 1/2 or more full (i.e., has 4 or more data characters)
00 = Interrupt flag bit is asserted while receive buffer is not empty (i.e., has at least 1 data character)
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 control bit has no effect
0 = Address Detect mode is disabled
bit 4
RIDLE: Receiver Idle bit (read-only)
1 = Receiver is Idle
0 = Data is being received
bit 3
PERR: Parity Error Status bit (read-only)
1 = Parity error has been detected for the current character
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
0 = Framing error has not been detected
bit 1
OERR: Receive Buffer Overrun Error Status bit.
This bit is set in hardware and can only be cleared (= 0) in software. Clearing a previously set OERR bit
resets the receiver buffer and RSR to empty state.
1 = Receive buffer has overflowed
0 = Receive buffer has not overflowed
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
