Figure 3-26 Slave Mode Clock Timing

3.12 Quad Timer Timing

Table 3-16 Timer Timing1, 2

Operating Conditions: VSSIO=VSS = VSSA = 0V, VDDA =VDDIO=3.0–3.6V, VDD = 2.25–2.75V, TA = –40° to +85°C, CL < 50pF, fop = 80MHz

In the formulas listed, T = clock cycle. For 80MHz operation, T = 12.5ns.

2. Parameters listed are guaranteed by design.
