Name:
Address:
Access:
• DEV_ADDR: UDPHS Address
This field contains the default address (0) after power-up or UDPHS bus reset (read), or it is written with the value set by a
SET_ADDRESS request received by the device firmware (write).
• FADDR_EN: Function Address Enable
0 = Device is not in address state (read), or only the default function address is used (write).
1 = Device is in address state (read), or this bit is set by the device firmware after a successful status phase of a
SET_ADDRESS transaction (write). When set, the only address accepted by the UDPHS controller is the one stored in the
UDPHS Address field. It will not be cleared afterwards by the device firmware. It is cleared by hardware on hardware reset,
or when UDPHS bus reset is received.
• EN_UDPHS: UDPHS Enable
0 = UDPHS is disabled (read), or this bit disables and resets the UDPHS controller (write). Disable the UTMI transceiver.
The UTMI may disable the pull-up.
1 = UDPHS is enabled (read), or this bit enables the UDPHS controller (write).
• DETACH: Detach Command
0 = UDPHS is attached (read), or this bit pulls up the DP line (attach command) (write).
1 = UDPHS is detached, UTMI transceiver is suspended (read), or this bit simulates a detach on the UDPHS line and
forces the UTMI transceiver into suspend state (Suspend M = 0) (write).
See PULLD_DIS description below.
•
0 = Remote Wake Up is disabled (read), or this bit has no effect (write).
1 = Remote Wake Up is enabled (read), or this bit forces an external interrupt on the UDPHS controller for Remote Wake
UP purposes.
An Upstream Resume is sent only after the UDPHS bus has been in SUSPEND state for at least 5 ms.
This bit is automatically cleared by hardware at the end of the Upstream Resume.
