Serial Interface Status and
Control Register (SISC)
Primary register address: "A"hex
Serial Transmit Buffer (STB)
–
Byte Write
Primary register address: "9"hex
T
he STB is the transmit buffer of the SSI. The SSI transfers the transmit buffer into the shift regi
s-
ter and star
ts shifting with
the
most significant bit.

ulti-
C
hip
L
ink 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
R
eceive
ACK
nowledge status/control bit for MCL mode
RACK = 0, transmit acknowledge in next receive telegram
RACK = 1, transmit no acknowledge in last receive telegram
TACK
T
ransmit
ACK
nowledge status/control bit for MCL mode
TACK = 0, acknowledge received in last transmit telegram
TACK = 1, no acknowledge received in last transmit telegram
SIM
S

I
nterrupt
M
ask
SIM = 1, disable interrupts
SIM = 0, enable serial interrupt. An interrupt is generated.
IFN
I
nterrupt
F

N
ction
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
S
erial interface buffer
R
ea
DY
status flag
SRDY = 1,
in receive mode: receive buffer empty
n transmit mode: transmit buffer full
SRDY = 0,
in receive mode: receive buffer full
in transmit mode: transmit buffer empty
ACT
Transmission
ACT
ive 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
