2.8.5
VIP Microcode Write Operation (FIFO B)
A microcode write operation is required to download microcode to the TVP5040 program RAM after power-up reset.
During the write cycle, the internal microprocessors program counter resets and points to location zero in the program
RAM and remains reset. Upon completion of the write operation, a microprocessor CLEAR-RESET operation is
required. This is performed by writing into the 017F register to clear reset and resume the microprocessor function.
(There is no specific data requirement to be written into the 017F register; any data resumes the microprocessor
function.)

VIP Microcode Read Operation (FIFO C)
The data written during the microcode write operation can be read from the TVP5040 program RAM. During the read
cycle, the internal microprocessors program counter resets and points to location zero in the program RAM and
remains reset. Upon completion of the read operation, a microprocessor CLEAR-RESET operation is required. This
is performed by writing into the 017F register to clear reset and resume the microprocessor function. (There is no
specific data requirement to be written into the 017F register; any data resumes the microprocessor function.)
