Video Processor Video Memory Address Space. This register allows PCI access to the memory mapped Video Processor configura-
tion registers. Bits [11:0] are read only (0000 0000 0000) indicating a 4 KB memory address range. See Table 7-9 on page 338 for bit for-
mats and reset values of the registers accessed through this base address register.

Video Processor Module - Video Processor Registers - Function 4
Located in the PCI Header Registers of F4 are three Base
Address Registers (F4BARx) used for pointing to the regis-
ter spaces designated for Video Processor support.
F4BAR0 is for Video Processor Configuration, F4BAR1 is
reserved, and F4BAR2 is for VIP configuration.
