Description
Bidirectional 8-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 trig-
ger input with or without 12K pull-high resistor.
Bidirectional 8-bit input/output port. Software* instructions determine the output or
Schmitt trigger input with or without pull-high resistor.
This pin is an I/O port. NMOS open drain output with pull-high resistor and can be
used as DATA or CLOCK line of PS2. This pin can be configured as a wake-up in-
put by mask option.
This pin is an I/O port. NMOS open drain output with pull-high resistor and can be
used as DATA or CLOCK line of PS2. This pin can be configured as a wake-up in-
put by mask option.
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 trig-
ger input with or without pull-high resistor.
PC2 also as external interrupt input pin. PE0 determine whether rising edge or fall-
ing edge of PC2 to trigger the INT circuit.
Bidirectional 4-bit input/output port. Software* instructions determine the CMOS
output or Schmitt trigger input with or without pull-high resistor.
Bidirectional 8-bit input/output port. Software* instructions determine the CMOS
output or Schmitt Trigger input with or without pull-high resistor.
