(4) Timing of On-Chip Supporting Modules
Tables 22.9 and 22.10 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, and IRQ2), the watchdog timer, and the 8-bit timer (channels 0 and
1).
