Timing of On-Chip Peripheral Modules: Tables 28.8 to 28.11 show the on-chip peripheral
module timing. The only on-chip peripheral 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 28.8 Timing of On-Chip Peripheral Modules (1)
Conditions: V_CC = 2.7 V to 3.6 V, V_CCB = 2.7 V to 5.5 V, V_SS = 0 V, ø = 32.768 kHz*,
2 MHz to maximum operating frequency, T_a = –20 to +75°C
