Wake-up
Pull-high
or None
Bidirectional 8-bit input/output ports
E ach bit can be configured as a wake-up input by mask option.
Software instructions determine the CMOS output or schmitt
trigger input with or without a pull high resistor (by mask option).
PB0~PB7
I/O
Pull-high
or None
Bidirectional 8-bit input/output ports
Software instructions determine the CMOS output or schmitt
trigger input with or without a pull high resistor (by mask
option).

Crystal or
RC
OSC1 and OSC2 are connected to an RC network or a crystal
(by mask option) for the internal system clock. In the case of RC
operation, OSC2 is the output terminal for 1/4 system clock.
PD0~PD7
I/O
Pull-high
or None
Bidirectional 8-bit Input/Output port. Software instructions
determine the CMOS output or schmitt trigger input with or
without a pull high resistor (by mask option).
