28.2.3
The following shows the clock timing, control signal timing, bus timing, and on-chip peripheral
function timing. For the AC characteristics test conditions, see figure 28.3.
Clock Timing: Table 28.20 shows the clock timing. The clock timing specified here covers clock
(ø) output and clock pulse generator (crystal) and external clock input (EXTAL pin) oscillation
settling times. For details of external clock input (EXTAL pin and EXCL pin) timing, see section
25, Clock Pulse Generator.
