III PERIPHERAL BLOCK: PRESCALER
1)Blocks that use an operating clock generated by the prescaler
•
•
•A/D converter
2)Blocks that use the clock supplied to the prescaler (the prescaler source clock)
•
•
•A/D converter
•Serial interface
•Ports
If none of the blocks in groups 1 and 2 above are used, turn off the prescaler (by setting PSCON in the power control register (0x40180) to "0"). If any of the blocks in groups 1 and 2 above are used, do not turn off the prescaler. Turning off the prescaler turns off the clock signal supplied to the blocks in group 2 above. Also, if only some of the circuits in group 1 above are used, turn off all the other circuits and stop clock supply from the prescaler to those circuits.
