Register Descriptions
The Multiplexer has 25 registers (refer to Table B-1). This section contains
a description of each register. Undefined register bits appear as "1" when the
register is read, and have no effect when written to.
You can write to the writable (W) registers and read from the readable (R)
registers which are listed in Table B-1.
