25.1 Comparator Voltage Reference
Control Registers
The CVREF module consists of the following Special
Function Registers (SFRs):
• CVRCON: Control Register for the Module
• CVRCONCLR, CVRCONSET, CVRCONINV:
atomic Bit Manipulation Registers for CVRCON
Table 25-1 provides a brief summary of all CVREF
module related registers. Corresponding registers
appear after the summary, followed by a detailed
description of each register.
