Hello guys, im doing the prj using L9369 and the customer said that they can not provide PWM for SYNC5 pin so could I change to 1 of GPIO pin that received data from PWM to SPI transfer data ? i find out that the input filtering time of GPIO is 2 to 9 us and the period of SYNC5 is 5ms so I think its ok, but I don't know what s gonna happened if the SYNC1 and SYNC5 signal is not synchronized , is it ok ?
