Notes:
1. 000 mode powers-down the PLL sections and forces the outputs low. To ensure glitch-free start and
stop of the CPU and BUS clocks, enter 000 from 001 and exit 000 through 001.
2. Select is FS0, Fs1 = 00, 01, 10, 11.
3. F is the value of CPU, ECPU & BUS. F value is 66.6, 60, 50 or 33.3 as selected by FS(0:1).
