EM785840/5841/5842

8-bit Micro-controller

If enable PLL, CPU will operate at normal mode (high frequency). Otherwise, it will run at green mode

(low frequency, 32768 Hz).

PORT70 's wakeup function is controlled by IOCF bit 3. It's falling edge or rising edge trigger (controlled

by CONT register bit7).

PORT71 's wakeup function is controlled by IOCF bit 4. It’s falling edge trigger.

PORT73 's wakeup function is controlled by IOCF bit 5. It is falling edge trigger.
