Multi-Chip Link activation
MCL = 1, multi-chip link disabled. This bit has to be set to '0' during
MCL = 0, connects SC and SD, additionally to the internal multi-chip link pads
Receive ACKnowledge status/control bit for MCL mode
RACK = 0, transmit acknowledge in next receive telegram
RACK = 1, transmit no acknowledge in last receive telegram
Transmit ACKnowledge status/control bit for MCL mode
TACK = 0, acknowledge received in last transmit telegram
TACK = 1, no acknowledge received in last transmit telegram
Serial Interrupt Mask
SIM = 1, disable interrupts
SIM = 0, enable serial interrupt. An interrupt is generated
Interrupt FuNction
IFN = 1, the serial interrupt is generated at the end of telegram
IFN = 0, the serial interrupt is generated when the SRDY goes low (i.e., buffer

Transmission ACTive status flag
ACT = 1, transmission is active, i.e., serial data transfer. Stop or start conditions
ACT = 0, transmission is inactive
