EM73P362

4-BIT MICRO-CONTROLLER FOR LCD PRODUCT

STOP OPERA

OP OPERA

OP OPERATION MODE

TION MODE

During STOP operation mode, CPU holds the system’s internal status with a low power consumption, for

the STOP mode, the system clock will be stopped in the STOP condition and system need a warm up time

for the stability of system clock running after wakeup.

The STOP operation mode is controlled by Port 16 and released by P0(0..3)/WAKEUP 0 3

.. .

STOP operation mode condition :

1. Osc stop 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 STOP release.

Release condition :

1. Release STOP operation mode by the falling edge of any one of P0(0..3)/WAKEUP 0 3

.. .

2. Osc start to oscillating.

3. Warm-up time passing.

4. According PC to execute the following program.

Note : There are 4 independent mask options for wakeup function in EM73P362. So, the wakeup function

P0(0..3)/WAKEUP 0 3

are enabled or disabled independently.

IDLE OPERA

IDLE OPERATION MODE

TION MODE

The IDLE operation mode retains the internal status with low power consumption without stopping the

system clock function and LCD display.

The IDLE operation mode is controlled by Port 19 and released by P0(0..3)/WAKEUP 0..3 or the internal

timing generator.
