Reset values are shown for 80-pin devices; individual unimplemented bits should be interpreted as ‘-’. 3: The PLLEN bit is only available in specific oscillator configuration; otherwise, it is disabled and reads as ‘0’. See Section 2.6.4 “PLL in INTOSC Modes”. 4: RA6/RA7 and their associated latch and direction bits are individually configured as port pins based on various primary oscillator modes. When disabled, these bits read as ‘0’. 5: RG5 and LATG5 are only available when Master Clear is disabled (MCLRE configuration bit = 0); otherwise, RG5 and LATG5 read as ‘0’. 6: Bit 7 and Bit 6 are cleared by user software or by a POR. 7: Bit 21 of TBLPTRU allows access to the device configuration bits. |
