MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
Master Address Byte
A4:A0
Contains the address of the desired register.
R/
W
Contains information about a read or a write operation.
If R/
W
= 1, the second byte of master contains no valid
information, slave just transmits back register data.
If R/
W
= 0, the master sends data to be written in the
second byte, slave sends concurrently contents of
selected register prior to write operation, write data is
latched in the
SMARTMOS
register on rising edge of
SS
.
Parity P
The parity bit is equal to “0” if the number of 1 bits is an even
number contained within R/
W
,A4:A0. If the number of 1 bits is
odd, P equals “1”. For example, if R/
W
= 1, A4:A0 = 00001,
then P equals “0.”
The parity bit is only evaluated during a write operation.
Bit X
Not used.
Master Data Byte
Contains data to be written or no valid data during a read
operation.
Slave Status Byte
Contains the contents of the System Status Register ($0c)
independent of whether it is a write or read operation or which
register was selected.
Slave Data Byte
Contains the contents of selected register. During a write
operation it includes the register content prior to a write
operation.
