Table 25.8 Bus Timing
Conditions (regular specifications):
VCC = 4.5 V to 5.5 V, PVCC = 4.5 V to 5.5 V,
AVCC = 4.5 V to 5.5 V, AVrefh = 4.5 V to AVCC,
VSS = PLLVSS = AVSS = AVrefh = 0 V,
Ta = â40°C to +85°C
Conditions (wide-range specifications): VCC = 3.0 V to 3.6 V, PVCC = 4.5 V to 5.5 V,
AVCC = 4.5 V to 5.5 V, AVrefh = 4.5 V to AVCC,
VSS = PLLVSS = AVSS = AVrefh = 0 V,
Ta = â40°C to +125°C
