Receiver C and U Data Buffer Transfer Disable
This bit is used to enable and disable buffer transfers between the Receiver Access (RA) and User Access (UA) buffers for both channel
status (C) and user (U) data.
Buffer transfers are typically disabled to allow the customer to read C and U data from the DIR UA buffer through the SPI or I²C serial host
interface. Once read, the RA-to-UA buffer transfer can be re-enabled to allow the RA buffer to update the contents of the UA buffer in real
time.

Disabled; the user may read C and U data from the DIR UA buffers.
