25.3.4 Timing of On-Chip Supporting Modules
Tables 25.8 to 25.10 show the on-chip supporting module timing. The only on-chip supporting
modules that can operate in subclock operation (ø = 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 25.8 Timing of On-Chip Supporting Modules (1)
Condition: VCC = 2.7 V to 3.6 V, VCCB = 2.7 V to 5.5 V, VSS = 0 V, ø = 32.768 kHz*, 2 MHz to
maximum operating frequency, Ta = –20 to +75°C
