RSVD FIFO_ADDRESS
VIP_FIFO_R_W_ADDR Bit Descriptions
Bit Name Description
31:9 RSVD Reserved. Set to 0.
8:0 FIFO_ADDRESS FIFO ADDRESS. FIFO address for which a FIFO read or write occurs. The data is writ-
ten/read via the FIFO Data register (VIP Memory Offset 74h). Note that the 256x64 bit
FIFO is mapped as a 512x32 bit memory.
VIP Memory Offset 74h
Type R/W
Reset Value xxxxxxxxh

FIFO_DATA
VIP_FIFO_DATA Bit Descriptions
Bit Name Description
31:0 FIFO_DATA FIFO Data. When the FF_R/W bit is set (VIP Memory Offset 04h[24] = 1), data written to
this register is stored in FIFO_ADDR (VIP Memory Offset 70h[7:0]). When the FF_R/W
bit is reset, data from the FIFO corresponding to the address in the FIFO_ADDR is
returned
