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
