If the user code switches MCU clock sources, a dummy MCU cycle should be
included after the clock switch is written to PLLCON.
Description
PLL clock source.
00 = low power 131 kHz oscillator.
01 = precision 131 kHz oscillator.
10 = external 32.768 kHz crystal.
11 = reserved.
Reserved. These bits should be written as 0 by user code.
PLLKEY0
Write only
0x000000AA
PLLKEY0 is the PLLCON prewrite key. PLLCON is
a keyed register that requires a 32-bit key value to be
written before and after PLLCON.
PLLKEY1
Write only
0x00000055
PLLKEY1 is the PLLCON postwrite key. PLLCON
is a keyed register that requires a 32-bit key value to
be written before and after PLLCON.

Read/write
This 8-bit register allows user code to
dynamically select one of three oscillator
sources as the PLL source clock.
