Fig 5.2 Valid Data
5.2 Data Transfer Format
5.2.1 Master transmits data to slave (write cycle)
§
S : Start
§
A : Acknowledge by slave
§
P : Stop
§
RW : The LSB of 1
ST byte to decide whether current cycle is read or write cycle.
RW=1 read cycle, RW=0 write cycle.
§
SUBADDRESS : The address values of PAS106BCA-323/PAS106BBA-323 internal control
registers
(Please refer to PAS106BCA-323/PAS106BBA-323
register description)
During write cycle, the master generates start condition and then places the 1
st byte data that are combined
slave
address
(7
bits)
with
a
read/write
control
bit
to
SDA
line.
After
slave(PAS106BCA-323/PAS106BBA-323) issues acknowledgment, the master places 2
nd byte (sub-address)
data on SDA line. Again follow the PAS106BCA-323/PAS106BBA-323 acknowledgment, the master places
the 8 bits data on SDA line and transmit to PAS106BCA-323/PAS106BBA-323 control register (address was
assigned by 2
nd byte). After PAS106BCA-323/PAS106BBA-323 issue acknowledgment, the master can
generate a stop condition to end of this write cycle. In the condition of multi-byte write, the
PAS106BCA-323/PAS106BBA-323 sub-address is automatically increment after each DATA byte transferred.
