(4) Timing of On-Chip Supporting Modules

Tables 26.63 shows 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).

Table 26.63 Timing of On-Chip Supporting Modules

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), Ta = –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), Ta = –40 to +85°C (wide-

range specifications)

Condition C: V

CC = 2.7 V to 3.6 V, VSS = 0 V, φ = 32.768 kHz

*, 2 MHz to maximum operating

frequency, T
