I
The STMPE16M31PX has 2 physical I
settings.
Table 5.
The features that are supported by the I
The features that are not supported are:
Device operation
Start condition
A Start condition is identified by a falling edge of SDA while SCL is stable at high state. A
Start condition must precede any data/command transfer. The device continuously
monitors for a Start condition and does not respond to any transaction unless one is
encountered.
Stop condition
A Stop condition is identified by a rising edge of SDA while SCL is stable at high state. A
Stop condition terminates the communication between the slave device and bus master. A
read command that is followed by NoAck can be followed by a Stop condition to force the
slave device into idle mode. When the slave device is in idle mode, it is ready to receive the
next I
operation to registers.
