Selects CCLKx as the PLL reference clock
Selects CCLK0
Selects VCO÷2. The VCO frequency is scaled by a factor of 2 (low VCO
frequency range).
Test mode with the PLL bypassed. The reference clock is substituted for the
internal VCO output. MPC9772 is fully static and no minimum frequency limit
applies. All PLL related AC characteristics are not applicable.
QC2 and QC3 are in phase with QC0 and QC1
Outputs disabled (high-impedance state) and device is reset. During reset/
output disable the PLL feedback loop is open and the internal VCO is tied to
its lowest frequency. The MPC9772 requires reset after any loss of PLL lock.
Loss of PLL lock may occur when the external feedback path is interrupted.
The length of the reset pulse should be greater than one reference clock
cycle (CCLKx). The device is reset by the internal power-on reset (POR)
circuitry during power-up.
