SC
The start complete (SC) field is set when a read or write access is initiated. The
device will clear the SC bit once the read or write access completes. During a block
access, if the SC bit is reset, the access will terminate.

RWAD
Read/write address (RWAD) bits are used to identify the address of internal
memory-mapped resources to be accessed, or the lowest address (i.e., lowest
unsigned value) for a block move (CNT > 0). The address range for a block move is
from RWAD to RWAD + CNT.
NOTE: The RWD field of the UDI register is shared with the WD field of the RWA
register.

RW
The read/write (RW) field can be configured to allow selection of a read or a write
access.
