Section 26 Electrical Characteristics
(1) Clock Timing
Table 26.34 shows the clock timing. The clock timing specified here covers clock ( ) 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 24, Clock
Pulse Generator.
