22.3.3 Timing of On-Chip Peripheral Modules
Tables 22.7 to 22.10 show the on-chip peripheral module timing. The only on-chip peripheral
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).
