The datasheet says the following:

So does that mean that when making a design that uses the SC18, the GPIO6 must have a pull-up resistor to it?

Hello Joshua,

Yes, the GPIO6 must have a pull-up resistor to ensure proper boot.

Best regards,

Tomas

Hello,

I'd like to know why the SC18 in the evaluation board boots up even though there's no pull-up resistor on its GPIO6?

I am trying to connect the bridge to a half duplex UART (one wire arrangement),

I was thinking to activate through one of the I/O a one shot signal to control an external tri-state output buffer of the TX to enable Tx only when master on the UART expecting returned message. i was not sure if it can be done with the help of I2C on/off command
