USB REGIO (Read)

Address <15:15> = 1 indicates a read to the MCU register space; Address <15:15> = 0 indicates a read to the DSP register space. When accessing DSP register space, the MCU must write the address to be read to the USB Regis- ter I/O Address register.

Bit 15 of the USB Register I/O Address register starts the transaction, and bit 14 is set to zero to indicate a READ. The data read will be placed into the USB Register I/O Data register.

USB REGIO (register read) is a three-stage control transfer with an IN data stage. Stage 1 is the SETUP stage, stage 2 is the data stage involving the IN packet, and stage 3 is the status stage. See Table 20 on page 25 for details about the USB REGIO (register read) fields.

DSP Code Download

Since EP0 only has a max packet size of 8, downloading DSP code on EP0 can be inefficient when operating on a UHCI controller which only allows fixed amount of control transactions per frame. Therefore, to gain better through- put for code download, downloading of DSP code involves synchronizing a control SETUP command on EP0 with BULK OUT commands on endpoints 1, 2, or 3. Each end- point has an associated DSP download address that is set by using USB REGIO (Write) command.
