A/D Result Register High Byte
A/D Result Register Low Byte
x = unknown, u = unchanged, – = unimplemented, read as ‘0’, q = value depends on condition.
Shaded cells are not used for A/D conversion.
RE3 port bit is available only as an input pin when MCLRE bit in configuration register is ‘
This register is not implemented on PIC18F2X31 devices.
These bits are not implemented on PIC18F2X31 devices.
These pins may be configured as port pins depending on the Oscillator mode selected.
ANS5 through ANS8 are available only on the PIC18F4X31 devices.
Not available on 28-pin devices.
