Name and Function

T0 (P3.4): Timer 0 external input

T1 (P3.5): Timer 1 external input

No alternate function on this pin

No alternate function on this pin

Reset: A high on this pin for two machine cycles while the oscillator is running, resets the device.

An internal diffused resistor to VSS permits a power-on reset using only an external capacitor to

VCC.

Programming Supply Voltage: This pin receives the 12.75V programming supply voltage

during EPROM programming. During normal operation, VPP pin must be tied to Vcc.

(VPP)

Crystal 1: Input to the inverting oscillator amplifier and input to the internal clock generator

circuits.

O

Crystal 2: Output from the inverting oscillator amplifier
