TEST_MODE
Function
These bits are undefined.
This bit enables the UART test mode. When the test mode bit is set
the UART clock is switched to the PCI bus clock. The faster clock
reduces the size of the test vectors and also shortens the run time of
the test vectors. The power up state is normal mode enabled.
0 - Normal mode enabled.
1 - UART test mode enabled.

Host Interface - Memory Page
The memory page register is a four bit register used to access one of 16 memory pages within the
AUDIOPCI chip. This register can be read or written but any unused bits are undefined on read back.
