5.3 Registers Controlling Clock Generator
(1) Clock operation mode select register (OSCCTL)
Remark f
The following eight registers are used to control the clock generator.
This register selects the operation modes of the high-speed system and subsystem clocks.
OSCCTL can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
