Description
Bidirectional 2-bit input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without a pull-high resistor (de-
termined by pull-high option: port option). The PWM0/PWM1 output func-
tion are pin-shared with PD0/PD1 (dependent on PWM options).
Schmitt trigger reset input. Active low.
Positive power supply
Negative power supply, ground.
OSC1, OSC2 are connected to an RC network or a Crystal (determined by
options) for the internal system clock. In the case of RC operation, OSC2 is
the output terminal for 1/4 system clock.

TEST mode input pin.
It disconnects in normal operation.
Absolute Maximum Ratings
Supply Voltage ...........................VSS-0.3V to VSS+6.0V
Input Voltage..............................VSS-0.3V to VDD+0.3V
Storage Temperature ............................-50°C to 125°C
Operating Temperature...........................-40°C to 85°C
Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maximum Ratings² may
cause substantial damage to the device. Functional operation of this device at other conditions beyond those
listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliabil-
ity.
