Control Signal Timing: Table 28.21 shows the control signal timing. The only external interrupts
that can operate on the subclock (ø = 32.768 kHz) are NMI and IRQ0, 1, 2, 6, and 7.
Table 28.21 Control Signal Timing
Condition A:
V_CC = 5.0 V ± 10%, V_CCB = 5.0 V ± 10%, V_SS = 0 V, ø = 32.768 kHz,
2 MHz to maximum operating frequency, T_a = –20 to +75°C (normal
specification product), T_a = –40 to +85°C (wide range temperature
specification product)
Condition B:
V_CC = 4.0 V to 5.5 V, V_CCB = 4.0 V to 5.5 V, V_SS = 0 V, ø = 32.768 kHz,
2 MHz to maximum operating frequency, T_a = –20 to +75°C (normal
specification product), T_a = –40 to +85°C (wide range temperature
specification product)
Condition C:
V_CC = 2.7 V to 3.6 V, V_CCB = 2.7 V to 5.5 V, V_SS = 0 V, ø = 32.768 kHz,
2 MHz to maximum operating frequency, T_a = –20 to +75°C
