Control register zero establishes the QCLK with prescaler parameter fields and de-
fines whether external multiplexing is enabled. All of the implemented control register
fields can be read or written, reserved fields read zero and writes have no effect. They
are typically written once when the software initializes the QADC64, and not changed
afterwards.

Bits in this register control the direction of the port QA pin drivers when pins are configured for I/
O. Setting a bit configures the corresponding pin as an output; clearing a bit configures the cor-
responding pin as an input. This register can be read or written at any time.
