The OPTION2 register is a 6-bit wide, write-only regis-
ter which contains various control bits to configure the
added features on the PIC16HV540. A Power-on Reset
sets the OPTION2<5:0> bits.
Example 4-2 illustrates how to initialize the OPTION2
register.

All Power-on Resets will disable the
Brown-out Detect circuit. All subsequent
resets will not disable the Brown-out
Detect if enabled.

PCWU: Wake-up on Pin Change
1 = Disabled
0 = Enabled
SWDTEN: Software Controlled WDT Enable bit
1 = WDT is turned off it the WDTEN configuration bit = 0
0 = WDT is on if the WDTEN configuration bit = 0; if WDTEN bit = 1, then SWDTEN is ‘don’t care’
RL: Regulated Voltage Level Select bit
1 = 5 volt
0 = 3 volt
SL: Sleep Voltage Level Select bit
1 = RL bit setting
0 = 3 volt
BODL: Brown-out Voltage Level Select bit
1 = RL bit setting, but SL during SLEEP
0 = 3 volt
BODEN: Brown-out Enabled
1 = Disabled
0 = Enabled
