MSM
Modular Stop Mode
MSM = 1, modulator stop mode disabled (output masking off)
MSM = 0, modulator stop mode enabled (output masking on) - used in modulation modes
for generating bit streams which are not sub multiples of 8 bit.

SDD
Serial Data Direction
SDD = 1, transmit mode – SD line used as output (transmit data). SRDY is set by a
transmit buffer write access
SDD = 0, receive mode – SD line used as input (receive data). SRDY is set by a
receive buffer read access
