Master transmits a START
Master transmits the MCM20027 Slave Calling Ad-
dress with “WRITE” indicated (BYTE=66
01100110
MCM20027 slave sends acknowledgment by forc-
ing the SDATA Low during the 9th clock, if the Call-
ing Address was received
Master transmits the MCM20027 Register Address
MCM20027 slave sends acknowledgment by forc-
ing the SDATA Low during the 9th clock after re-
ceiving the Register Address
Master transmits the data to be written into the reg-
ister at the previously received Register Address
MCM20027 slave sends acknowledgment by forc-
ing the SDATA Low during the 9th clock after re-
ceiving the data to be written into the Register
Address
Master transmits STOP to end the write cycle
Master transmits a START
Master transmits the MCM20027 Slave Calling Ad-
dress with “WRITE” indicated (BYTE=66
01100110
MCM20027 slave sends acknowledgment by forc-
ing the SData Low during the 9th clock, if the Calling
Address was received
Master transmits the MCM20027 Register Address
MCM20027 slave sends acknowledgment by forc-
ing the SData Low during the 9th clock after receiv-
ing the Register Address
Master transmits a Repeated START
Master transmits the MCM20027 Slave Calling Ad-
dress with “READ” indicated (BYTE = 67
01100111
MCM20027 slave sends acknowledgment by forc-
ing the SDATA Low during the 9th clock, if the Call-
ing Address was received
At this point, the MCM20027 transitions from a
“Slave-Receiver” to a “Slave-Transmitter”
MCM20027 sends the SCLK and the Register Data
contained in the Register Address that was previ-
