Universal Serial Bus Interface with On-The-Go
Two operations, wake-up and read/write, can be performed with the ULPI Viewport. Wake-up operation
puts the ULPI interface into normal operation mode and re-enables the clock if necessary. A wakeup
operation is required before accessing the registers when ULPI interface is operating in low-power mode,
serial mode, or carkit mode. The ULPI state can be determined by reading the sync. state bit (ULPISS). If
this bit is a 1, ULPI interface is running in normal operation mode and can accept read/write operations.
If the ULPISS indicates a 0, read/write operations are not able to execute. Undefined behavior results if
ULPISS equals 0 and a read or write operation is performed. To execute a wakeup operation, write all 32
bits of the ULPI Viewport where ULPIPORT is constructed appropriately and the ULPIWU bit is 1 and
ULPIRUN bit is 0. Poll the ULPI viewport until ULPIWU is 0 for the operation to complete.
To execute a read or write operation, write all 32 bits of the ULPI Viewport where ULPIDATWR,
ULPIADDR, ULPIPORT, and ULPIRW are constructed appropriately and the ULPIRUN bit is 1. Poll the
ULPI Viewport until ULPIRUN is 0 for the operation to complete. After ULPIRUN is 0, ULPIDATRD is
valid if the operation was a read.
The polling method above could also be replaced by an interrupt driven routine using the ULPI interrupt
defined in the USB_USBSTS and USB_USBINTR registers. When a wakeup or read/write operation
complete, the ULPI interrupt is set.
There are several optional features that system software may need to enable or disable as part of system
configuration. These bits are contained in the interface and OTG control registers of the ULPI PHY
register set. These registers also contain bits controlled by the link dynamically and therefore should only
be modified by system software using the set/clear access method. Direct writes to these registers could
have harmful side effects to the standard USB operations. The optional bits are as follows: bits 3 through
7 in the interface control register and bits 6 and 7 in the OTG control register. Refer to the ULPI
Specification Revision 1.1 for further information on the use of the optional features.

Writes to the ULPI through the viewport can substantially harm standard
USB operations. Read operations should have no harmful side effects to
standard USB operations.
