as battery low detection. The 7-bit current-type D/A converter and PWM device provide complete
speech output mechanism.
The instruction set of HE8P160 is quite easy to learn and simple to use. Only about thirty
instructions with four-type addressing mode are provided. Most of instructions take 3 oscillator
clocks (machine cycles). The processing power is enough for most of battery operation system.
