Description
CIS should start with a CISTPL_DEVICE tuple. (Allows operation at 5.0 volts)
The CISTPL_DEVICE_OC tuple allows operation at 3.3 volts.
This tuple specifies the manufacturer ID and product ID codes (0x0279 and 0x950B
respectively).
This tuple specifies the function of the device, in this case the tuple states the device
is a serial port.
This tuple is the function extension tuple, and provides more detailed information
about the function of the device, and provides the following information:
• Serial port includes a 16550 compatible UART.
• Space, Mark, Odd and Even parity
• 5, 6, 7, 8 bit chars
• 1, 1.5 and 2 stop bit operation.
