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 PIC18F2331/2431 devices.
These bits are not implemented on PIC18F2331/2431 devices.
These pins may be configured as port pins depending on the oscillator mode selected.
ANS5 through ANS8 are available only on the PIC18F4331/4431 devices.
Not available on 28-pin devices.
