Section 8 Bus State Controller (BSC)
High-level duties of 35% and 50% can be selected for the RD signal using the RD duty bit
(RDDTY) in BCR. When RDDTY is set to 1, the high-level duty is 35% of the T1 state, enabling
longer access times for external devices. Only set to 1 when the operating frequency is a minimum
of 10 MHz.
