(1) Event A occurs when WR + CS0 + CS1 = 0 (boolean).
(2) Event B occurs when WR + CS0 + CS1 = 1 (boolean).

Intel-mode interface write cycle timing (12 MHz clock)
Note
1. Legacy AT bus PCs may not satisfy this requirement as they are not ISA compatible. An application fix is available
in the
“SAA5284 Users Guide”.
