FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
R/W
includes the information if it is a read or a write operation.
If R/W = 1 (read operation), second byte of master
contains no valid information, slave just transmits back
register data.
If R/W = 0 (write operation), 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 registers on rising edge
of SS.
Parity P
completes the total number of 1 bits of (R/W,A[4-0]) to an
even number. e.g. (R/W,A[4-0]) = 100001 -> P0 = 0.
The parity bit is only evaluated during write operations and
ignored for read operations.
Bit X
not used
Master Data Byte
This byte includes data to be written or no valid data during
a read operation.
Slave Status Byte
This byte always includes the contents of the system
status register ($0C), independent if it is a write or read
operation, or which register was selected.
Slave Data Byte
This byte includes the contents of selected register, during
write operation in includes the register content prior to write
operation.
