19.3 Wake-up Timer Mode
In the Wake-up Timer mode, the on-chip oscillator is not
stopped. Except the Prescaler(only 2048 devided ratio),
Timer0 and Timer2, all functions are stopped, but the on-
chip RAM and Control registers are held. The port pins out
the values held by their respective port data register, port
direction registers.
The Wake-up Timer mode is activated by execution of
STOP instruction after setting the bit WAKEUP of
CKCTLR to “1”. (This register should be written by
byte operation. If this register is set by bit manipulation
instruction, for example “set1” or “clr1” instruction, it
may be undesired operation)
