The following table describes the USB interface presented to the host by the MCU micro
controller.
Vendor Request Name ID Description
VR_GET_FLASH_REV 0xA6 Returns a revision code of the “MCU” firmware
VR_GET_FPGA_INFO 0xA7
VR REBOOT 0xAD
VR_CONFIG 0xAF Causes MCU to go through configuration
sequence (Media Card)
VR_FLASH_VERSION 0xB2 Reads version of flash code
VR_DISPLAY_FPGA_INFO 0xB3
VR_CHECK_FPGA_INFO 0xB4
VR_CHECK_FPGA_CONFIG 0xB5 Returns a string representing if the selected FPGA
is configured
FLASH_VERSION_ADDR 0x08 Value to go into upper address register
(MCU_XADDR
VR_SET_EP6TC 0xBB Sets the size of the bulk transfer (Read) buffer. You
must set this to a value equal to the SIZE field of
the USB Bulk transfer
VR_SETUP_CONFIG 0xB7 This vendor request must be called to select an
FPGA for configuration prior to a bulk transfer
containing the configuration stream for that
FPGA.
VR_END_CONFIG 0xBD This vendor request de-selects an FPGA after
configuration and returns the configuration status
of that FPGA (DONE signal)
VR_MEM_MAPPED
(Config Read)
(Config Write) 0xBE This vendor request reads or writes to the address
space of the MCU. This vendor request can be
used with the configuration register map above to
accomplish any configuration task.
VR_CLEAR_FPGA 0x90 Clears the selected FPGA of configuration data.
VR_BOARD_VERSION 0xB9 Returns a byte representing the type of board
Each vendor request has a direction, request type, request, and value, size and buffer pointer
fields. The request type is always TYPE_VENDOR. The request field is the ID listed in the
table above. The value and data in the buffer pointer fields are vendor-request specific. The size
field is the number of bytes in the buffer. The details of how to implement a vendor request are
outside the scope of this manual.
6.2.1 VR_CLEAR_FPGA
This vendor request clears an FPGA.
