(4) Timing of On-Chip Supporting Modules

Tables 25.9 and 25.10 show the on-chip supporting module timing. The only on-chip supporting

modules that can operate in subclock operation (

φ = 32.768 kHz) are the I/O ports, external

interrupts (NMI and IRQ0, 1, 2, 6, and 7), the watchdog timer, and the 8-bit timer (channels 0 and

1).

Timing of On-Chip Supporting Modules (1)

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
