Legend: — = unimplemented, read as ‘0’. Reset values are shown in hexadecimal.
Note 1: Bit available only when MCLRE = 0.
2: Bits are available only when the primary oscillator is disabled (POSCMD1:POSCMD0 = 00); otherwise read as ‘0’.
3: 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’.
