General Description
The MCS7705 controller provides bridging between
the Universal Serial Bus (USB) port, and a Parallel
Printer port. This device contains all the necessary
logic to communicate with the host computer via
the USB Bus. It supports Printers with hardware
accelerated SPP mode.
In addition, the MCS7705 contains a 3.3V regulator
and operates in Bus-Powered mode.
The MCS7705 has a reduced frequency (6MHz)
crystal oscillator. This combination of features
allows significant cost savings in system design
along with straightforward implementation of
Parallel Printer port functionality into PC peripherals
using the host’s USB port.

Vendor Specific Command Parameters
Brequest: specifies whether to Read or Write
0x0E = write to the application register.
0x0D = read from the application register.
Wvalue: Specifies the Application Number.
0x0100 is the application number for the Parallel Printer port.
0x0200 is reserved.
0x0000 is the application number provided for accessing the other control registers to control the
Parallel Printer port (i.e. Setting the clock frequency, etc.)
xx specifies the Byte value to be written into the register.
Windex: Is the offset of the register to Read/Write.
Wlength: Is the length of the data we are going to read or write.
