Register Map Bit Control
In this view, any bit can be selected and altered. The changed value will be written to the actual
device control register by hitting the "enter" or "return" key on the PC keyboard, or by simply
moving the cursor to a different bit field. When any of these completing actions is done, the
hexadecimal value column entry for that register will also be updated.
In this view, hexadecimal values may also be directly changed in the "Hex Val" column. The
changed value will be written to the actual device control register by hitting the "enter" or "return"
key on the PC keyboard, or by simply moving the cursor to a different bit field.

Register Map Update Bits (write-only bits)
The bits known as "update bits" are commands to the device that are not physically stored in the
device control registers. These bits are displayed in the Register Map view as the present user
preference. This preference may be altered at any time. When writing the device from the
Register Map view, the displayed preferences for each update bit will be used when writing the
respective register which contains that update bit.

Audio Codec Register Control
This panel gives simple hexadecimal read and write control to all of the registers in the device.
Both the register address and register data are in hexadecimal format. If the control bus is set up
in a write-only format, then reading the device is not possible, and attempts to read the device will
result in an error message from the GUI Application software.
