Function
Port 0 (P0):
• 8-bit I/O port
• Can be used as real-time output port (4 bits x 2).
• Can be set in input or output mode bitwise.
• Pins set in input mode can be connected to internal pull-up
resistors by software.
• Can drive transistor.
Port 1 (P1):
• 8-bit I/O port
• Can be set in input or output mode bitwise.
• Pins set in input mode can be connected to internal pull-up
resistors by software.
• Can drive LEDs.
Port 2 (P2):
• 8-bit input port
• P20 cannot be used as general-purpose port pin (non-maskable
interrupt). However, its input level can be checked by interrupt
routine.
• P22 through P27 can be connected to internal pull-up resistors
by software in 6-bit units.
• P25/INTP4/ASCK/SCK1 pin can operate as SCK1 output pin if
so specified by CSIM1.
Port 3 (P3):
• 8-bit I/O port
• Can be set in input or output mode bitwise.
• Pins set in input mode can be connected to internal pull-up
resistors by software.
Port 6 (P6):
• P60 through P63 is dedicated ports for output.
• P66 and P67 can be set in input or output mode bitwise.
• Pins set in input mode can be connected to internal pull-up
resistors by software.
Port 7 (P7):
• 8-bit I/O port
• Can be set in input or output mode bitwise.
