• Apply voltage of 5 V to V
• Applies voltage supplied to pull-down resistors.
• RC oscillator pins for system clock.
• Reset input pin for active “L”.
• Internal pull-up resistors connected between the RESET and V
• Serial transfer is possible by inputting “L” signal.
• Clock for serial transfer is input.
• Read a clock twice with 2 MHz sampling clock and judge if it is a noise or not.
• Serial data is output.
• During reset it is in high-impedance state.
• Serial data is input.
• Read a clock twice with 2 MHz sampling clock and judge if it is a noise or not.
• Pin for ordinary output or digit output.
• At reset this port is set to V
• Pin for digit output or segment output.
• At reset this port is set to V
• Pin for segment output.
