Function
Port 0 (P0):
• 7-bit I/O port
• Input/output can be specified in 1-bit units.
• Whether specifying input mode or output mode, an on-chip pull-up
resistor can be specified in 1-bit units by means of software.
Port 1 (P1):
• 8-bit input only port
Port 2 (P2):
• 8-bit I/O port
• Input/output can be specified in 1-bit units.
• Whether specifying input mode or output mode, an on-chip pull-up
resistor can be specified in 1-bit units by means of software.
Port 3 (P3):
• 8-bit I/O port
• Input/output can be specified in 1-bit units.
• Whether specifying input mode or output mode, an on-chip pull-up
resistor can be specified in 1-bit units by means of software.
Port 4 (P4):
• 8-bit I/O port
• Input/output can be specified in 1-bit units.
• When used as an input port, an on-chip pull-up resistor can be
specified by means of software.
• LEDs can be driven directly.
Port 5 (P5):
• 8-bit I/O port
• Input/output can be specified in 1-bit units.
• When used as an input port, an on-chip pull-up resistor can be
specified by means of software.
• LEDs can be driven directly.
