Data lanes control uses a simple FSM to sequence entry and exit of Ultra Low Power mode. This FSM observes inputs from the control registers and based on these inputs it generates PPI outputs for ULP mode.
The State descriptions are presented in Table 12-1543.
| State (ulps_data_fsm_st_r) | Description |
|---|---|
| DATA_LN_IDLE | Idle state. In this state HS transmission can be issued if clock lane is in HS mode. |
| DATA_LN_ULPS_REQ | Request to enter ULP state. Waiting for activation ULP confirmed by tx_ulps_active_n input. |
| DATA_LN_ULPS_ACTIVE | ULPS for data lanes is active. Waiting for ulps_req_sync being low to exit ULPS. |
| DATA_LN_ULPS_EXIT | ULPS exiting, waiting for time defined in ULPS_DATA_WAKEUP_TIME register. |
