6.1 Device Response to the Reset

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 presense 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.

If the slave device is preset, PDIAG- is checked for up to 31 seconds.

30 sec.
