Section 12 Bus State Controller (BSC)
Memory Card Interface Burst Timing: In this LSI, when the IC memory card interface is
selected, page mode burst access mode can be used, for read access only, by setting bits A5BST1
and A5BST0 in BCR1 for physical space area 5, or bits A6BST1 and A6BST0 in BCR1 for area
6. This burst access mode is not stipulated in JEIDA version 4.2 (PCMCIA2.1), but allows high-
speed data access using ROM provided with a burst mode, etc.
Burst access mode timing is shown in figures 12.27 and 12.28.
