PLLCON Prewrite Key PLLKEY0
Name: PLLKEY0
Address: 0xFFFF0410
Access: Write only
Key: 0x000000AA
Function: PLLCON is a keyed register that requires a 32-bit key
value to be written before and after PLLCON. PLLKEY0 is the
prewrite key.
PLLCON Postwrite Key PLLKEY1
Name: PLLKEY1
Address: 0xFFFF0418
Access: Write only
Key: 0x00000055
Function: PLLCON is a keyed register that 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.
Table 46. PLLCON MMR Bit Designations
Bit
31 to 3
2
1 to 0
If 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.
Not Used. Must be written as 0 by user software.
PLL Clock Source.
00 = low power 131 kHz oscillator.
01 = precision 131 kHz oscillator.
10 = external 32.768 kHz crystal.
11 = reserved.
