***************************************************************************

AX_FIRM.ASM: This assembly file supports the USB 1.0 standard requests and will enumerate
the 8x930Ax as a single function device.
The descriptor sets up the device for loopback on EP1, 2 & 3 as follows:
Configuration 1: 6 endpoints
EP1 - IN, Bulk, 64 bytes
    - OUT, Bulk, 64 bytes
EP2 - IN, Interrupt, 8 bytes
    - OUT, Bulk, 8 bytes
EP3 - IN, Isochronous, 8 bytes
    - OUT, Isochronous, 8 bytes
Note: Only one configuration is listed in the device descriptor.  But there are endpoint
descriptors in the firmware for a second configuration.

ONE_OH.INC: This file contains equates related to the operations under USB Spec. rev 1.0
It also includes equates for 8x930 register manipulation.

8X930AX.INC: This file contains the special function registers for the 930Ax controller.

MINOR SYNTAX CHANGES MAY NEED TO BE MADE TO THIS FILE DEPENDING ON THE COMPILER
YOU ARE USING.

 Remarks about this code:
*************************
 The code is in an absolute format starting at location 00:4000 hex
 This location should be used if this code is to be downloded through
 a serial RS232 port to the 8x930AX\Hx board with RISM programmed in
 the EPROM. The main code starts at label "main" located at 004080.
 There is no need to include the configuration bytes in this code
 because RISM already takes care of that.

 If users want to adapt this code to their own board or if they want
 to change the EPROM provided with the board with their own EPROM,
 then they need to relocate the code. They need to change the
 starting location to 0FF:0000 hex and the label main to 0FF:0080.
 They will also need to program the Chip Cconfiguration Bytes.

 This code should run on all assemblers provided by third party
 vendors. Minimum changes may be required. Users may need to change
 the include files, and use the ones provided by the Third party
 vendor they are using.
