PLL0 Lock bit. 1=PLL0 Locked. 0=PLL0 Unlocked.
Force the PLL0 Lock sequence to start. 1=Enable Force Lock. This bit is not self clearing.
Reserved - Always set to zero (0).
Status of the PLL0 lock count. The PLL0 lock bit will assert when the count reaches 0x4B0. The lock count
is driven off of xtal, so it should be asserted after 50 us.
