C Microcode Read Operation
Data read during the microcode write operation will be read from the TVP5031 program RAM. During the read cycle
the microprocessor will reset and point to location zero in the program and will remain reset. Upon completion of the
read operation, a microprocessor clear-reset operation is required. This is performed by writing into the 7F register
to clear reset and resume the microprocessor function. (There is no specific data requirement to be written into the
7F register, any data will resume microprocessor function.)
