Technical Data
VCOT — VCO test (Test mode only)
MCS — Module clock select
LCK — Synthesizer lock detect
WEN — WAIT enable

the PLL is near the specified frequency. The high bandwidth driver is
then disabled and BWC is cleared by internal circuitry. Reset clears
this bit.
This bit is used to isolate the loop filter from the VCO for testing
purposes. VCOT is always set when AUTO = 1 when running in
automatic mode. This bit is writable only in test mode. Reset sets this
bit.
Reset clears this bit.
This bit is used as an indicator for software that it is all right to set
BCS.
This bit determines whether the 4XCLK is disconnected from
VCOOUT during WAIT and connected to EXTAL. Reset clears this
bit.
When set, the CPU will respond to a WAIT instruction by first stacking
For More Information On This Product,
1 = Loop filter operates as specified by AUTO and BWC.
0 = Low bandwidth mode of the PLL filter is disabled.
1 = 4XCLK is the source for the SCI and timer divider chain.
0 = EXTAL is the source for the SCI and timer divider chain.
1 = The PLL has stabilized.
0 = The PLL is not stable.
1 = Low-power WAIT mode selected (PLL set to ‘idle’ in WAIT
0 = Do not alter the 4XCLK during WAIT mode.
