6.1.3 Response to software reset

The master device does not check the DASP- signal for a software reset. If a
slave device is present, the master device checks the PDIAG- signal for up to 15
seconds to see if the slave device has completed the self-diagnosis successfully.
After the slave device receives the software reset, the slave device shall report its
presence and the result of the self-diagnostics to the master device as described
below:
PDIAG- signal: negated within 1 ms and asserted within 30 seconds
When the IDD is set to a slave device, the IDD asserts the DASP- signal when
negating the PDIAG- signal, and negates the DASP- signal when asserting the
PDIAG- signal.
