DRV8353R: DRV8353RS VCP power-on procedure

$

Part Number:DRV8353R

I made 5V(VDD5) and 3.3V(VDD_3V3) power by external power and didn't use internal buck from DRV8353RS.

I expected VCP turned on when ENABLE went to rise without spi communication.

However, VCP weren't enabled and in addition NFAULT was reserved high.

I don't understand the power on procedure of VCP.
