Field
CME
VDIV
3:0
5
Clock Monitor Enable — Determines if a reset request is made following a loss of external clock indication. The
CME bit must only be set to a logic 1 when either the MCG is in an operational mode that uses the external clock
(FEE, FBE, PEE, PBE, or BLPE) or the external reference is enabled (ERCLKEN=1 in the MCGC2 register).
Whenever the CME bit is set to a logic 1, the value of the RANGE bit in the MCGC2 register must not be changed.
0 Clock monitor is disabled.
1 Generate a reset request on loss of external clock.
VCO Divider — Selects the amount to divide down the VCO output of PLL. The VDIV bits establish the
multiplication factor (M) applied to the reference clock frequency.
