These bits are used in comparing PCI Address bits 31-24 for each memory window (0-4). These
bits are used in conjunction with the System Memory Map 0-4 Start Address and System
Memory Map 0-4 End Address registers.
Misc Control 3
Bit 6 — Multimedia Expand
This bit allows 24-bit video from the PC Card. If the Multimedia Arm bit and Multimedia Enable
bit are both set to ‘1’, this bit causes CE2 and D[15:8] to be tristated on the 16-bit PC Card bus, and
also tristates A[25:4].
Bit 7 — Multimedia Arm
No multimedia operation can take place without first setting this bit to ‘1’; the bit provides an
overriding control mechanism. By setting only bit 0 of index 16h, the Multimedia Arm bit ensures
that multimedia operation is not inadvertently set by software or point enablers.
Device Identification and Implementation Scheme
There are four byte-wide registers with read-only device information, and four byte-wide read/
write registers that contain specific system-implementation information. These registers are found
in revisions of the PD6729 that have the value 21h/E1h in the Chip Information register (index
1Fh).
