Serial Interface Status and Control Register (SISC)
Primary register address: 'Hex
Bit 3Bit 2Bit 1Bit 0
SISC write

Reset value: 1111b
SISC read
- - -
TACK
ACT
SRDY
Reset value: xxxxb
MCL
Multi-Chip Link activation
MCL = 1, multi-chip link disabled. This bit has to be set to '0' during
transactions to/from the internal EEPROM
MCL = 0, connects SC and SD, additionally to the internal multi-chip link pads
RACK
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
TACK
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
SIM
Serial Interrupt Mask
SIM = 1, disable interrupts
SIM = 0, enable serial interrupt. An interrupt is generated
IFN
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
becomes empty/full in transmit/receive mode)
SRDY
Serial interface buffer ReaDY status flag
SRDY = 1,
in receive mode: receive buffer empty
in transmit mode: transmit buffer full
SRDY = 0,
in receive mode: receive buffer full
in transmit mode: transmit buffer empty
ACT
Transmission ACTive status flag
ACT = 1, transmission is active, i.e., serial data transfer. Stop or start conditions
are currently in progress.
ACT = 0, transmission is inactive
