POWER SAVING FUNCTION ( Sleep / Hold functlon ) only for single clock system
During sleep and hold condition, CPU holds the system’s internal status with a low power consumption, for
the sleep mode, the system clock will be stoped in the sleep condition and system need a warm up time for
the stability of system clock running after wakeup . In the other way, for the hold mode, the system clock
does not stop at all and it does not need a warm-up time any way.
The sleep and hold mode is controlled by Port 16 and released by P0(0..3)/WAKEUP0..3 or P8(2..3)/
WAKEUPC..D.

Sleep and hold condition:
1. Osc stop ( sleep only ) and CPU internal status held .
2. Internal time base clear to "0".
3. CPU internal memory ,flags, register, I/O held original states.
4. Program counter hold the executed address after sleep release.
Release condition:
1. Osc start to oscillating.(sleep only).
2. Warm-up time passing ( sleep only ).
3. According PC to execute the following program.
There is one kind of sleep/hold release mode .
1. Edge release mode:
Release sleep/hold condition by the falling edge of any one of P0(0..3)/WAKEUP0-3 or P8(2..3)/
WAKEUPC..D.
Note : There are 6 independent mask options for wakeup function in EM73220. So,the wakeup
function of P0(0..3)/WAKEUP0..3 and P8(2..3)/WAKEUPC..D are enabled or disabled indepen-
dently.
