MCT8316Z: FGOUT halt delay from BRAKE signal

Hello,

My customer is designing MCT8316Z0TRGFR and observing a strange motor operation. Can you help check if it's expected?

- When BRAKE (#38) is applied, motor halts operation after 400 ms. Meanwhile, there's 222 ea of hall sensor values. Is it normal? When they check the operation with other motor control IC and the same motor, they see FGOUT hault immediately when BRAKE arises.

C1 (yellow) : pin #40 FGOUT

C2 (green) : pin #38 BRAKE 

- Register setting is as below. The other setting values are all default.

void SPI_SetupDrv(void)
{
    SPI_Write(0x03,0x03); //unlock SPI
    SPIDelay();
    SPI_Write(0x04,0x02); //SR = 200V/us, Asynch rectification w/ digital Hall
    SPIDelay();
}
