23.3 Power-Saving Modes Control
Registers
Power-Saving modes control consists of the following
Special Function Registers (SFRs):
• OSCCON: Control Register for the Oscillators
Module
OSCCONCLR, OSCCONSET, OSCCONINV:
Atomic Bit Manipulation Write-only Registers for
OSCCON
• WDTCON: Control Register for the Watchdog
Timer Module
WDTCONCLR, WDTCONSET, WDTCONINV:
Atomic Bit Manipulation Write-only Registers
for WDTCON
• RCON: Control Register for the Resets Module
RCONCLR, RCONSET, RCONINV: Atomic Bit
Manipulation Write-only Registers for RCON
The following table summarizes Power-Saving modes
registers. Corresponding registers appear after the
summary, followed by a detailed description of each
register.
