2. General Description
The SH79F1617 is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch
structure, that helps the SH79F1617 can perform more fast operation speed and higher calculation performance, if compare
SH79F1617 with standard 8051 at same clock speed.
The SH79F1617 retains most features of the standard 8051. These features include internal 256 bytes RAM, UART and
Int0-3.In addition, the SH79F1617 provides external 512 bytes RAM, It also contains 16K bytes Flash memory block both for
program and data. Also the ADC and PWM timer functions are incorporated in SH79F1617.
For high reliability and low cost issues, the SH79F1617 builds in Watchdog Timer, Low Voltage Reset function. And SH79F1617
also supports two power saving modes to reduce power consumption.

RST
the device will be reset by A low voltage on this pin longer than 10us, an internal
I resistor about 100kΩ to VDD, So using only an external capacitor to GND can cause
a power-on reset.
