A.12 AC Characteristics
This section describes ac timing characteristics for each peripheral system.
A.12.1
Freescale Semiconductor
Typical data was characterized at 5.0 V, 25°C unless otherwise stated.
This is the shortest pulse that is guaranteed to be recognized as a reset pin request. Shorter pulses are not guaranteed to
override reset requests from internal sources.
When any reset is initiated, internal circuitry drives the RESET pin low for about 34 cycles of t
clock frequency changes to the untrimmed DCO frequency (freset = (f
reset to 0; and there is an extra divide-by-two because BDIV is reset to 0:1. After other resets, trim stays at the pre-reset value.
Timing is shown with respect to 20% V
