I2C Microcode Read Operation
Data read during the microcode read operation will be read from the TVP5020 Program RAM. During the
read cycle the microprocessor resets and points to location zero in the program and remains reset. Upon
completion of the read operation, the microprocessor requires a restart operation. To perform a clear–reset
requires writing into the 7F register to clear reset and resume microprocessor function. (The 7F register
requires no specific data written into the register, any data will resume microprocessor function).
