(2) Control Signal Timing

Table 25.7 shows the control signal timing. The only external interrupts that can operate on the

subclock (

φ = 32.768 kHz) are NMI and IRQ0, IRQ1, IRQ2, IRQ6, and IRQ7.

Control Signal Timing

Condition A: V

CC = 5.0 V ±10%, VSS = 0 V, φ = 32.768 kHz, 2 MHz to maximum operating

frequency, T

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

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

Condition B: V

CC = 4.0 V to 5.5 V, VSS = 0 V, φ = 32.768 kHz, 2 MHz to maximum operating

frequency, T

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

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

Condition C: V

CC = 3.0 V to 5.5 V, VSS = 0 V, φ = 32.768 kHz, 2 MHz to maximum operating

frequency, T

a = –20 to +75°C
