Please tell me the state(CMOS output or Open drain or Hi-Z) of PWR#_I2C_SDA pin(26pin) during the following each operation period?
Case1: During Reset.
Case2:Immedietely after reset cancellation(Initial setting).
Case3:During I2C operation.
Case4:Transition period of I2C operation END to /PWR operation start.
Case5:Immedietely after /PWR operation is started(Initial setting)
Hello Arai san,
Case1: During RESET, PWR#/I2C_SDA pin will be Hi-Z.
Case2: After RESET is de-asserted, the pin will be configured for I2C_SDA to look for external EEPROM if any connected to boot from it.
Case3: During I2C operation, it will be used for I2C operation only which is I/O.
Case4: It will be Hi-Z while switching.
Case5: It will be an Output pin.
