CK10 (32ms), CK8 (8ms) & CK6 (2ms).
Output ports.
Input/Output ports.
Input/Output ports.
External interrupt request control input pin.
System reset pin.
Output only for outputting the signal to drive the transistor for light.
Output only for outputting the 4kHz/2kHz/1kHz modulation signal.
Also can be used to output the non-modulation signal.
(+)Power supply pin.
* For Ag version, apply (+) side to VDD & VDD1 together.
For other than Ag version, apply (+) side to VDD & VDD2 together.
Power supply pin for LCD driver power supply.
(--)Power supply pin.
