zoom video

The PCI1031 allows the implementation of the zoom video proposal before the PCMCIA. Zoom video is

supported by setting bit 6 of the card control register (see

card control register) in the TI extension registers.

Setting bit 6 puts address lines A25–A4 of the PC Card interface in the high-impedance state. These lines can

then be used to transfer video and audio data directly to the appropriate controller. Address lines A3–A0 can

still be used by the PCI1031 to access PC Card CIS registers for PC Card configuration (see Figure 7).
