Access Type:
• DEV_ADDR: UDPHS Address
Read:
This field contains the default address (0) after power-up or UDPHS bus reset.
Write:
This field is written with the value set by a SET_ADDRESS request received by the device firmware.
• FADDR_EN: Function Address Enable
Read:
0 = Device is not in address state.
1 = Device is in address state.
Write:
0 = only the default function address is used (0).
1 = this bit is set by the device firmware after a successful status phase of a SET_ADDRESS transaction. When set, the
only address accepted by the UDPHS controller is the one stored in the UDPHS Address field. It will not be cleared after-
wards by the device firmware. It is cleared by hardware on hardware reset, or when UDPHS bus reset is received (see
above).
• EN_UDPHS: UDPHS Enable
Read:
0 = UDPHS is disabled.
1 = UDPHS is enabled.
Write:
