Freescale Semiconductor

Electrical and Thermal Characteristics

Figure 8 shows PIO, timer, and DMA signals.

Figure 8. PIO, Timer, and DMA Signal Diagram

Table 10 lists SIU input characteristics.

Table 9. AC Characteristics for SIU Inputs1

1 Input specifications are measured from the 50% level of the signal to the 50% level of the rising edge of CLKIN. Timings

are measured at the pin.
