- Process when pins are not used:
PIN TYPE “O” – Ensure that it is set to OPEN. DD or VSS even when it is unused. PIN TYPE “B” – If you are unsure about processing method on the pin description of pin layout table, please contact us.
- Note that incorrect processing of unused pins may result in defects.

- When IOVDD is power OFF, it is prohibition to apply the voltage to a 1.8 V pins*.
SDA, SCL, EIRQ tolerate 3 V input at the time of power off. The data in the EEPROM may be rewritten unintentionally if you do not keep specifications. And it is forbidden to power off during EEPROM access. The data in the EEPROM may be rewritten unintentionally. OIS driver and AF driver are recommended to set standby before VM power off.
