FIGURE 10. SLAVE MODE WRITE
NOTE: Successive WRITE accesses to the 82C237 must allow at least TCY as recovery time between accesses. A TCY recovery time must
be allowed before executing a WRITE access after a READ access.
FIGURE 11. SLAVE MODE READ
NOTE: Successive READ accesses to the 82C237 must allow at least TCY as recovery time between accesses. A TCY recovery time must
be allowed before executing a READ access after a WRITE access.
