To prevent this from happening, it is necessary for the master to wait until the I2C bus is free (that is, SCL high) before
generating a STOP condition, thus insuring that a valid STOP condition is generated. This provides the optimal
amount of delay and eliminates the need for a software-generated delay.
The I2C master must also wait until the I2C bus is free (that is, SCL high) before generating a START condition.
4.1.3.3 Implementation for PHI Bus
For PHI host interface-based applications, the interrupt request (INTREQ) pin (or interrupt status register polling) may
be used to determine when the TVP5031 is ready to proceed with host interface activity. This eliminates the need
for a software-generated delay.
