CPU interface timing
The AC characteristics of a CPU interface are measured on condition as follows.
The input conditions at the time of measurement
: VIH = 0.8×IOVDD,
VIL=0.2×IOVDD
The measurement points
: VIH = 0.65×IOVDD,
VIL=0.35×IOVDD
VOH = 0.65×IOVDD,
VOL=0.35×IOVDD
● CPU interface 1 (In the case of IOVDD≧2.65V)
