— = unimplemented, read as ‘0’. Reset values are shown in hexadecimal.
This bit is 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.
These bits are available only when the primary oscillator is disabled (POSCMD<1:0> = 00); otherwise read as ‘0’.
These bits are available only when the primary oscillator is disabled or EC mode is selected (POSCMD<1:0> = 00 or 11) and CLKO is disabled (OSCIOFNC = 0); otherwise read as ‘0’.
