Remarks
• Oscillation circuit
Internal oscillation feedback
resistor (Rf)
• CMOS hysteresis input
• CMOS hysteresis I/O pin with pull-up
control
CMOS output
CMOS hysteresis input (with input cut-
off function in standby mode)
Internal pull-up resistor (Rp)
< Note >
• The pull-up resistor is active when the
port is set as an input.
• CMOS hysteresis I/O pin
CMOS output
CMOS hysteresis input (with input cut-
off function in standby mode)
< Notes >
• The I/O port output and internal
resource output share the same out-
put buffer.
• The I/O port input and internal
resource input share the same input
buffer.
