TMS320F28377S: Default State of GPIO pin upon 1st Power up

Part Number: TMS320F28377S
Other Parts Discussed in Thread: TPS2640

Hi,

We're planning to use TMS320F28377S in our application.

We want to understand the default state of GPIO pin upon 1st power up of the MCU (no code present inside the MCU & MCU not programmed).

We have connected one GPIO from MCU to TPS2640's SHDN pin directly without any pullup to supply. Want to understand the behaviour of the TPS2640 IC when the MCU powers up for the very 1st time.

Kindly guide us in this regard.

Warm Regards,

Prahaladh S
