TABLE 4-3: REGISTER FILE SUMMARY (CONTINUED)
File Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Value on
POR, BOR
Details
on page:
Legend: x = unknown, u = unchanged, – = unimplemented, q = value depends on condition
Note 1: RA6 and associated bits are configured as port pins in RCIO and ECIO Oscillator mode only and read ‘0’ in all other oscillator
modes.
2: Bit 21 of the TBLPTRU allows access to the device configuration bits.
3: These registers are unused on PIC18F6X80 devices; always maintain these clear.
4: These bits have multiple functions depending on the CAN module mode selection.
5: Meaning of this register depends on whether this buffer is configured as transmit or receive.
6: RG5 is available as an input when MCLR
is disabled.
7: This register reads all ‘0’s until the ECAN module is set up in Mode 1 or Mode 2.
