There is no address phase associated with reading the VBI FIFO 1 register. This register is read-only and is always
set to 0x37.
2.8.4.5 VBI FIFO (FIFO A)
The VBI FIFO stores sliced VBI data in the format described in section 2.9.1. Data may be read from the FIFO at the
average rate of 1 data byte per 3 cycles (1 data cycles, 2 wait cycles) when the VIPCLK is at maximum speed.

There is no address phase associated with reading the VBI FIFO. FIFO polling is implemented.
2.8.5
VIP Microcode Write Operation (FIFO B)
The data written during the microcode write operation will be written to the TVP5040 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 the microprocessor function. (There is no specific data requirement to be written
into the 7F register, any data will resume the microprocessor function.)
