(4) Timing of On-Chip Supporting Modules
Tables 26.23 to 26.25 show the on-chip supporting module timing. The only on-chip supporting
modules that can operate in subclock operation ( = 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).
