Operations

(3) Slumber mode

In this mode, the (deep) Power Save mode is set for the interface circuit.

The device switches to Slumber mode when the following occurs:

•The device receives the PMREQ_P signal from the host and responds with the PMACK signal

•The device sends the PMREQ_S signal and the host responds with PMACK signal.

The device cannot switch to Slumber mode if the following condition is satisfied:

•The device responds with the PMNAK signal because it is not waiting for commands.

The device returns to Active mode from Slumber mode when the following condition is satisfied:

•The device receives the COMRESET or ComWake signal from the host.
