Chapter 2 Clocks and Reset Generator (S12CRGV6)
The following conditions apply when the PLL is in automatic bandwidth control mode (AUTO = 1):
The PLL can also operate in manual mode (AUTO = 0). Manual mode is used by systems that do not
require an indicator of the lock condition for proper operation. Such systems typically operate well below
the maximum system frequency (f

The TRACK bit is a read-only indicator of the mode of the filter.
The TRACK bit is set when the VCO frequency is within a certain tolerance,
the VCO frequency is out of a certain tolerance,
The LOCK bit is a read-only indicator of the locked state of the PLL.
The LOCK bit is set when the VCO frequency is within a certain tolerance,
when the VCO frequency is out of a certain tolerance,
Interrupt requests can occur if enabled (LOCKIE = 1) when the lock condition changes, toggling
the LOCK bit.
ACQ is a writable control bit that controls the mode of the filter. Before turning on the PLL in
manual mode, the ACQ bit should be asserted to configure the filter in acquisition mode.
After turning on the PLL by setting the PLLON bit software must wait a given time (t
entering tracking mode (ACQ = 0).
After entering tracking mode software must wait a given time (t
