(4) Timing of On-Chip Supporting Modules
Tables 25.45 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).
