I/O
Wake-up
Pull-high
or None
Bidirectional 2-bit input/output port. Each 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
pull-high resistor.
PC4~PC7
I/O
Pull-high
or None
Bidirectional 4-bit input/output port. Software* instructions deter-
mine the CMOS output or schmitt trigger input with or without
pull-high resistor.
PD0~PD7
I/O
Pull-high
or None
Bidirectional 8-bit input/output port. Software* instructions deter-
mine the CMOS output or schmitt trigger input with or without
pull-high resistor.
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.
