22.2.3
The USB Status register reports the transaction status
within the SIE. When the SIE issues a USB transfer
complete interrupt, USTAT should be read to determine
the status of the transfer. USTAT contains the transfer
endpoint number, direction and Ping-Pong Buffer
Pointer value (if used).
The USTAT register is actually a read window into a
four-byte status FIFO, maintained by the SIE. It allows
the microcontroller to process one transfer while the
SIE processes additional endpoints
When the SIE completes using a buffer for reading or
writing data, it updates the USTAT register. If another
USB transfer is performed before a transaction
complete interrupt is serviced, the SIE will store the
status of the next transfer into the status FIFO.

USB STATUS REGISTER (USTAT)
The data in the USB Status register is
valid two SIE clocks after the TRNIF inter-
rupt flag is asserted.
In low-speed operation with the system
clock operating at 48 MHz, a delay may
be required between receiving the TRNIF
interrupt and processing the data in the
USTAT register.

Clearing the transfer complete flag bit, TRNIF, causes
the SIE to advance the FIFO. If the next data in the
FIFO holding register is valid, the SIE will reassert the
interrupt within 6 T
data is present, TRNIF will remain clear; USTAT data
will no longer be reliable.
