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