6.10 Register Read
Reading the MCM20014 registers is accomplished with
the following I2C transactions (see
Figure 26
):
Master transmits a START
Master transmits the MCM20014 Slave Calling Ad-
dress with
WRITE
indicated (BYTE=66
h
, 102
d
,
01100110
b
)
MCM20014 slave sends acknowledgment by forc-
ing the SData Low during the 9th clock, if the Calling
Address was received
Master transmits the MCM20014 Register Address
MCM20014 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 MCM20014 Slave Calling Ad-
dress with
READ
indicated (BYTE = 67
h,
103
d
,
01100111
b
)
MCM20014 slave sends acknowledgment by forc-
ing the SDATA Low during the 9th clock, if the Call-
ing Address was received
At this point, the MCM20014 transitions from a
Slave-Receiver
to a
Slave-Transmitter
MCM20014 sends the SCLK and the Register Data
contained in the Register Address that was previ-
ously received from the master; MCM20014 transi-
tions to slave-receiver
Master does not send an acknowledgment (NAK)
Master transmits STOP to end the read cycle
