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 TVP5041 is ready to proceed with host interface activity. This eliminates the need
for a software-generated delay.
4.1.3.4 Implementation for VIP
For VIP host interfaced-based application, the slave-terminate and master-retry mechanisms are used to handle the
latency after microprocessor restart. TVP5041 slaves terminate all VIP access until the microprocessor initialization
is completed. Meanwhile, the VIP master repeatedly retries the current VIP access until it is accepted by the
TVP5041. This eliminates the need for a software-generated delay.
