Control Data

Contains control register data.

It is essential that all reserved registers and bits are not changed from their reset state. If reserved bits

are changed, then internal test modes may be invoked, which may change some input pins to output

pins, and may completely change the definition of some functions and signals. Reserved bits in regis-

ters, and reserved registers, may not return a known state when read, and should be ignored. Registers

28 and 15 are read only. Other non-reserved registers are write only. The CS8130 can be set to echo

back register write commands to verify correct reception of the control settings.
