This section describes the DC and AC electrical specifications for the DUART interface of the
MPC8548E.
7.1
DUART DC Electrical Characteristics
Table 20 provides the DC electrical characteristics for the DUART interface.
7.2
DUART AC Electrical Specifications
Table 21 provides the AC timing parameters for the DUART interface.

Notes:
1. Guaranteed by design.
2. fCCB refers to the internal platform clock.
3. Actual attainable baud rate will be limited by the latency of interrupt processing.
4. The middle of a start bit is detected as the 8th sampled 0 after the 1-to-0 transition of the start bit. Subsequent bit values are
sampled each 16th sample.
