(2) Control Signal Timing

Table 22.19 shows the control signal timing. The only external interrupts that can operate on the

subclock (ø = 32.768 kHz) are NMI and IRQ0, 1, and IRQ2.

Table 22.19 Control Signal Timing

Condition A: V

= 5.0 V ± 10%, V

= 0 V, ø = 32.768 kHz, 2 MHz to maximum operating

frequency, T

= –20 to +75°C (regular specifications),

= –40 to +85°C (wide-range specifications)

Condition B: V

= 4.0 V to 5.5 V, V

= 0 V, ø = 32.768 kHz, 2 MHz to maximum operating

frequency, T

= –20 to +75°C (regular specifications),

= –40 to +85°C (wide-range specifications)

Condition C: V

= 2.7 V to 3.6 V, V

= 0 V, ø = 32.768 kHz, 2 MHz to maximum operating

frequency, T

= –20 to +75°C
