VIP Microcode Write Operation
Data is written to the TVP5022 program RAM during the microcode write operation. During the write cycle,
the microprocessor resets and points to location zero in the program and remains reset. Following the first
data phase, the data phase is repeated until all microcode is written. The microprocessor requires a
clear-reset operation upon completion of the write operation. The host performs the reset by writing into the
7F register to clear reset and resume microprocessor function. (There is no specific data to be written into
the 7F register; any data will resume microprocessor function).

Video Module Interface (VMI) Host Interface
The VMI host port interface is configurable for three possible modes of operation. The mode of operation
is determined by attaching pullup or pulldown resistors to the GLCO, PALI, and FID terminals. Table 2–7
shows the various modes. (0=pulldown and 1=pullup)
