    6.1.1 Response to power-on After the master device (device 0) releases its own power-on reset state, the master device shall check a DASP- signal for up to 450 ms to confirm presence of a slave device (device 1). The master device recognizes presence of the slave device when it confirms assertion of

    6.1.2 Response to hardware reset Response to RESET- (hardware reset through the interface) is similar to the power-on reset. Upon receipt of hardware reset, the master device checks a DASP- signal for up to 450 ms to confirm presence of a slave device. The master device recognizes the presence of
