Section 23. 10-bit A/D Converter

A/D Result Registers
The ADRESH:ADRESL register pair is the location where the 10-bit A/D result is loaded at the
completion of the A/D conversion. This register pair is 16-bits wide. The A/D module gives the
flexibility to left or right justify the 10-bit result in the 16-bit result register. The A/D Format Select
bit (ADFM) controls this justification.
Figure 23-6
shows the operation of the A/D result justifica-
tion. The extra bits are loaded with ‘0’s’. When an A/D result will not overwrite these locations (A/D
disable), these registers may be used as two general purpose 8-bit registers.
