Legend:

— = unimplemented, read as ‘0’. Reset values are shown in hexadecimal.

Note

Bit available only when MCLRE = 0.

A read of RA1 and RA0 results in ‘0’ when debug is active on the PGC2/PGD2 pin.

A read of RA4 results in ‘0’ when debug is active on the PGC3/PGD3 pin.

These bits are not implemented in 20-pin devices.

Bits are available only when the primary oscillator is disabled (POSCMD1:POSCMD0 = 00); otherwise read as ‘0’.

Bits are available only when the primary oscillator is disabled or EC mode is selected (POSCMD1:POSCMD0 = 00 or 11) and CLKO is disabled (OSCIOFNC = 0); otherwise read as ‘0’.

Note

A read of RB1 and RB0 results in ‘0’ when debug is active on the PGEC1/PGED1 pins.

A read of RB4 results in ‘0’ when debug is active on the PGEC3/PGED3 pins.

PORTB bits, 11, 10, 6, 5 and 3, are not implemented in 20-pin devices.
