0 = Disable I
Serial Port Ground Select
1 = PORTD<1:0> ground reference is the RD5/AN5 pin.
0 = PORTD<1:0> ground reference is V
Serial Port Ground Select
1 = PORTC<7:6> ground reference is the RA1/AN1 pin.
0 = PORTC<7:6> ground reference is V
I
1 = PORTD<1:0> are used as the I
0 = PORTC<7:6> are used as the I
SMBus-Compatibility Select
1 = SMBus compatibility mode is enabled. PORTC<7:6> and PORTD<1:0> have
SMBus-compatible input thresholds.
0 = SMBus-compatibility is disabled. PORTC<7:6> and PORTD<1:0> have Schmitt Trig-
ger input thresholds.
Oscillator Output Select (available in IN mode only).
1 = Output IN oscillator signal divided by four on OSC2 pin.
0 = Disconnect IN oscillator signal from OSC2 pin.
OSC2 output port bit (available in IN mode only).
Writes to this location affect the OSC2 pin in IN mode. Reads return the value of the
output latch.
OSC1 input port bit (available in IN mode only).
Reads from this location return the status of the OSC1 pin in IN mode. Writes have no
effect.
