2. General Description
The SH79F161A is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch
structure, that helps the SH79F161A can perform more fast operation speed and higher calculation performance, if compare
SH79F161A with standard 8051 at same clock speed.
The SH79F161A retains most features of the standard 8051. These features include internal 256 bytes RAM, UART and
Int0-3.In addition, the SH79F161A 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 SH79F161A.
For high reliability and low cost issues, the SH79F161A builds in Watchdog Timer, Low Voltage Reset function. And
SH79F161A also supports two power saving modes to reduce power consumption.

*Note:
P0.2, P0.3, P0.4, P0.5 are configured as N-channel open drain I/O
The out most pin function has the highest priority, and the inner most pin function has the lowest priority (Refer to Pin
Configuration Diagram. This means when one pin is occupied by a higher priority function (if enabled) cannot be used as the
lower priority functional pin, even when the lower priority function is also enabled. Until the higher priority function is closed by
software, can the corresponding pin be released for the lower priority function use.
