Section 12 Bus State Controller (BSC)
12.3.9
With this LSI, address pin pull-up can be performed when the bus is released by setting the PULA
bit in BCR1 to 1. The address pins are pulled up for a 4-clock period after BACK is asserted.
Figure 12.34 shows the address pin pull-up timing. Similarly, data pin pull-up can be performed
by setting the PULD bit in BCR1 to 1. The data pins should be pulled up when the data bus is not
in use. The data pin pull-up timing for a read cycle is shown in figure 12.35, and the timing for a
write cycle in figure 12.36.
