SGPIO Start Drive Lower Register x — SGSDLRx
The SGPIO Start Drive Lower Register x - SGSDLRx is used to program the drive
outputs order as they are shifted out on the serial bit stream. For example, after the
Vendor-Specific Code bits are shifted out on the SDataout pin, the user can choose in
which order each drive’s outputs are shifted out. This register controls the steering of
drive inputs[0:3] of the multiplexer block.
