FIGURE 33 – CPU READS FROM INTERNAL REGISTER TIMING
16MHz Clock
(Internal)
1. STRBD to IOEN (low) delay is two clock cycles. If contention occurs, delay is two clock cycles following release of bus.
2. CPU must release STRBD within 1.5µs of IOEN going active. READYD will go away within one clock cycle maximum.
