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 31 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 then negated within 31
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.
Max. 31 sec.
Max. 30 sec.
