PLLCON Prewrite Key
Name: PLLKEY0
Address: 0xFFFF0410
Access: Write only
Key: 0x000000AA
Function: This keyed register requires a 32-bit key value to be
written before and after PLLCON. PLLKEY0 is the prewrite key.
PLLCON Postwrite Key
Name: PLLKEY1
Address: 0xFFFF0418
Access: Write only
Key: 0x00000055
Function: This keyed register requires a 32-bit key value to be
written before and after PLLCON. PLLKEY1 is the postwrite key.
PLLCON Register
Name: PLLCON
Address: 0xFFFF0414
Default Value: 0x00
Access: Read/write
Function: This 8-bit register allows user code to dynamically
select the PLL source clock from three different oscillator sources.

POWCON Prewrite Key
Name: POWKEY0
Address: 0xFFFF0404
Access: Write only
Key: 0x00000001
Function: This keyed register requires a 32-bit key value to be
written before and after POWCON. POWKEY0 is the prewrite key.
POWCON Postwrite Key
Name: POWKEY1
Address: 0xFFFF040C
Access: Write only
Key: 0x000000F4
Function: This keyed register requires a 32-bit key value to
be written before and after POWCON. POWKEY1 is the post-
write key.
If the user code switches MCU clock sources, a dummy MCU cycle should be
included after the clock switch is written to PLLCON.
Description
Reserved. These bits should be written as 0 by user code.
PLL clock source.
00 = lower power, 131 kHz oscillator.
01 = precision 131 kHz oscillator.
10 = external 32.768 kHz crystal.
11 = reserved.
