4-bit output port. This N-ch open-drain output
port has an intermediate withstand voltage.
4-bit I/O port. Each bit can be set for input or
output.
Outputs the character data corresponding to R, G,
and B of the IDC display. The output is active-
high.
Outputs the blanking signal for cutting the
video signal of the IDC display. The output is
active-high.
Inputs the horizontal synchronizing signal of the
IDC display. The input must be active-low.
Inputs the vertical synchronizing signal of the IDC
display. The input must be active-low. The input
signal can generate an interrupt.
Input of port 1C and A/D converter
• P1C3 to P1C1
3-bit I/O port
• ADC1
Input of a 4-bit A/D converter
Input of a 4-bit A/D converter
Serial interface and input for port 0B, port 0A,
horizontal synchronizing signal counter, and
timer
• P0A3 to P0A0
4-bit I/O port. Each bit can be set for input or
output.
• P0B3 to P0B0
4-bit I/O port. Each bit can be set for input or
output.
• HSCNT
Inputs the count of the horizontal
synchronizing signal. The input is self-
biased.
• TMIN
Timer input. The pin inputs the commercial
power to be used for the clock.
• SI, SO, SCK
Input/output for the three-wire serial interface
• SI: Serial data input
• SO: Serial data output
• SCK: Shift clock input/output
• SDA, SCL
Input/output for the two-wire serial interface
• SCL: Serial clock input/output
• SDA: Serial data input/output
