CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER

Hyundai Micro Electronics 

GMS87C1102 / GMS87C1202

HYUNDAI MicroElectronics

8. PIN FUNCTION

VDD: Supply voltage.

VSS: Circuit ground.

RESET: Reset the MCU.

XIN: Input to the inverting oscillator amplifier and input to

the internal clock operating circuit.

XOUT: Output from the inverting oscillator amplifier. If

RC Option is used, the oscillator frequency divided by 4

(Xin/4) comes out from Xout pin.

RA0~RA7: RA is an 8-bit, CMOS, bidirectional I/O port.

RA pins can be used as outputs or inputs according to “1”

or “0” written in the Port Direction Register(RAIO).

In addition, RA serves the functions of the various special

features in Table 8-1.

RB0~RB4: RB is a 5-bit, CMOS, bidirectional I/O port.

RB pins can be used as outputs or inputs according to “1”

or “0” written in the Port Direction Register(RBIO).

RB serves the functions of the various following special

features.
