Figure 44. Bus Protocol
HS-Mode Protocol
When the bus is idle, both SDA and SCL lines are pulled high by the pull-up devices.
The master generates a start condition followed by a valid serial byte containing HS master code 00001XXX.
This transmission is made in F/S-mode at no more than 400 Kbps. No device is allowed to acknowledge the HS
master code, but all devices must recognize it and switch their internal setting to support 3.4 Mbps operation.
The master then generates a repeated start condition (a repeated start condition has the same timing as the start
condition). After this repeated start condition, the protocol is the same as F/S-mode, except that transmission
speeds up to 3.4 Mbps are allowed. A stop condition ends the HS-mode and switches all the internal settings of
the slave devices to support the F/S-mode. Instead of using a stop condition, repeated start conditions should be
used to secure the bus in HS-mode.
Attempting to read data from register addresses not listed in this section will result in 00h being read out.
I
2C UPDATE SEQUENCE
The TPS6236x requires a start condition, a valid I2C address, a register address byte, and a data byte for a
single update. After the receipt of each byte, the TPS6236x device acknowledges by pulling the SDA line low
during the high period of a single clock pulse. A valid I2C address selects the TPS6236x. The TPS6236x
performs an update on the falling edge of the acknowledge signal that follows the LSB byte.
