23.7.1
A command transmitted from the host by control transfer may require decoding and execution of
command processing on the application side. Whether command decoding is required on the
application side is indicated in table 23.3 below.

If decoding is not necessary on the application side, command decoding and data stage and status
stage processing are performed automatically. No processing is necessary by the user. An
interrupt is not generated in this case.
If decoding is necessary on the application side, the USB function module stores the command in
the EP0s FIFO. After normal reception is completed, the USBIER0/SETUP TS flag is set and an
interrupt request is generated. In the interrupt routine, 8 bytes of data must be read from the EP0s
data register (USBEPDR0S) and decoded by firmware. The necessary data stage and status stage
processing should then be carried out according to the result of the decoding operation.
