This register is used to set the definition of non-PCM data. The NPCM pin output and NPCM Register Flag
output follow this definition.
There are three types of non-PCM factors to be selected, based on OR logic.
NOTE
The DTSCD Register (Register 29h) must be '1' (that is, selected) in order to output the
DTSCD flag from the MPIO, MPO, and INT pins as DIR Flag outputs.
