Clock Timing: Table 28.5 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 on external clock input (EXTAL pin and EXCL pin) timing, see section
25, Clock Pulse Generator.
