TB2902HQ I
2C Bus Transmission Format
(1)
Write mode
In addition to usual transmission, it corresponds to continuation transmission and the auto
increment mode as a transmission format. After a transmission end, in case data transmission is
newly, it is necessary to open the term beyond 1 clock.
1)
Continuation transmission
(An address to change is specified. At this time, MSB of a sub-address is set as 0.)
2)
Auto increment
(Sub address are set to increment from N one by one. MSB of a sub-address is set as 1.)
(2)
Read mode
The slave address became the read mode by changing the 8 Bit of the slave address from 0 to 1.
The data output from TB2902HQ starts after the micro controller receives the ACK 1 bit which
follows a slave address.
Stop condition are shown in the under the map.
The micro controller shall send the stop condition P after it sent the reversed Acknowledge (high) in
case of the read mode finished.
The data transmission became not available condition if the micro controller intended to send the
stop condition P expect for this procedure because this IC occupies the data bus until the micro
controller send the start conditions again.
