Description
PE0~PE1
I/O
Pull-high
or None
Bidirectional input/output port. Software* instruction determine the CMOS output
or Schmitt Trigger input with or without pull-high resistor.
If PE0 output 1, rising edge of PC2 trigger INT circuit.
PE0 output 0, falling edge of PC2 trigger INT circuit.

Chip reset input. Active low. Built-in power-on reset circuit to reset the entire chip.
Chip can also be externally reset via RESET pin
OSC1

I
O
Crystal or
RC
OSC1, OSC2 are connected to an RC network or a crystal for the internal system
clock. In the case of RC operation, OSC2 is the output terminal for the 1/4 system
clock; A 110k
resistor is connected to OSC1 to generate a 2 MHZ frequency.
Note:
*: Software means the HT IDE (Holtek Integrated Development Environment) can be configured by mask
option.
