MCG_C6 field descriptions
Field Description
7
LOLIE0
Loss of Lock Interrrupt Enable
Determines if an interrupt request is made following a loss of lock indication. This bit only has an effect
when LOLS 0 is set.
0 No interrupt request is generated on loss of lock.
1 Generate an interrupt request on loss of lock.
6
PLLS
PLL Select
Controls whether the PLL or FLL output is selected as the MCG source when CLKS[1:0]=00. If the PLLS
bit is cleared and PLLCLKEN 0 is not set, the PLL is disabled in all modes. If the PLLS is set, the FLL is
disabled in all modes.
0 FLL is selected.
1
PLL is selected (PRDIV 0 need to be programmed to the correct divider to generate a PLL reference
clock in the range of 2–4 MHz prior to setting the PLLS bit).
5
CME0
Clock Monitor Enable
Enables the loss of clock monitoring circuit for the OSC0 external reference mux select. The LOCRE0 bit
will determine if a interrupt or a reset request is generated following a loss of OSC0 indication. The CME0
bit must only be set to a logic 1 when the MCG is in an operational mode that uses the external clock
(FEE, FBE, PEE, PBE, or BLPE) . Whenever the CME0 bit is set to a logic 1, the value of the RANGE0
bits in the C2 register should not be changed. CME0 bit should be set to a logic 0 before the MCG enters
any Stop mode. Otherwise, a reset request may occur while in Stop mode. CME0 should also be set to a
logic 0 before entering VLPR or VLPW power modes if the MCG is in BLPE mode.
0 External clock monitor is disabled for OSC0.
1 External clock monitor is enabled for OSC0.
VDIV0 VCO 0 Divider
Selects the amount to divide the VCO output of the PLL. The VDIV 0 bits establish the multiplication factor
(M) applied to the reference clock frequency. After the PLL is enabled (by setting either PLLCLKEN 0 or
PLLS), the VDIV 0 value must not be changed when LOCK 0 is zero.
