I. General Description
The EM785840 series are 8-bit RISC type microprocessor with low power, high speed CMOS technology. There
are 4Kx13 bits ROM within it. This integrated single chip has an on_chip watchdog timer (WDT), RAM, programmable
real time clock/counter, internal interrupt, power down mode, dual PWM (Pulse Width Modulation), 8-channel 10-bit
A/D converter and tri-state I/O.
