See Section 4.4 “Brown-out Reset (BOR)”. 2: These registers and/or bits are not implemented on 28-pin devices and are read as ‘0’. Reset values are shown for 40/44-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: The RE3 bit is only available when Master Clear Reset is disabled (MCLRE configuration bit = 0). Otherwise, RE3 reads as ‘0’. This bit is read-only. 5: 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’. |
