4. AC Characteristics (continued)
3) ISA Timing (continued)
Note) 1. 1: Differs depending on the operating mode.
2: 7 MCLK inactive periods are required for MEMW# and MEMR# after word writes to GR06, SR08, SR0D, and
SR15.
7 MCLK inactive periods are required for IOWR# and IORD# after word writes to CR1A.
20 MCLK inactive periods are required for MEMW# and MEMR# after word writes to SR07.
2. MCLK in the table refers to one clock period of the memory clock.
3. Values listed in the table apply when the external load capacitor is 50 pF. The output delay times will differ depending on
the external load capacitor.
