AC Characteristics

Figure 24.2 shows the test conditions for the AC characteristics.
LSI output pin
IOL = 1.6 A, IOH = 200 A
VT = 1.5 V
CL = 30 pF (The CL value includes capacitance of measuring jigs.)

Clock Timing

Table 24.4 shows the clock timing. The clock timing specified here covers oscillation stabilization
times for clock output (φ), clock pulse generator (crystal), and external clock input (EXTAL pin).
For details on external clock input (EXTAL pin and EXCL pin) timing, see section 21, Clock
Pulse Generator.
