This register defines the bInterval value which determines the length of the virtual frame
(see
This register indicates when the device sends a NAK handshake on an endpoint. Each Tx
and Rx endpoint has a bit in the EPTN and EPRN field respectively.
A bit in this register is cleared by writing a 1 to it.

Description
ULPI Read/Write control. This bit selects between running a read or
write operation.

ULPI Read/Write Run.
Writing the 1 to this bit will begin the read/write operation. The bit will
automatically transition to 0 after the read/write is complete. Once
this bit is set, the driver can not set it back to 0.
Remark: The driver must never executue a wakeup and a read/write
operation at the same time.
ULPI Wake-up.
Writing the 1 to this bit will begin the wakeup operation. The bit will
automatically transition to 0 after the wakeup is complete. Once this
bit is set, the driver can not set it back to 0.
Remark: The driver must never executue a wakeup and a read/write
operation at the same time.
