DUART
This section describes the DC and AC electrical specifications for the DUART interface of the MPC8610.
2.10.1
DUART DC Electrical Characteristics
Table 32 provides the DC electrical characteristics for the DUART interface.
2.10.2
DUART AC Electrical Specifications
Table 33 provides the AC timing parameters for the DUART interface.
2.11
Fast/Serial Infrared Interfaces (FIRI/SIRI)
The fast/serial infrared interfaces (FIRI/SIRI) implements asynchronous infrared protocols (FIR, MIR, SIR) that are defined by
IrDA (Infrared Data Association). Refer to http://www.IrDA.org for details on FIR and SIR protocols.
2.12
Synchronous Serial Interface (SSI)
This section describes the DC and AC electrical specifications for the SSI interface of the MPC8610.
2.12.1
SSI DC Electrical Characteristics

Notes:
1. Guaranteed by design.
2. Actual attainable baud rate will be limited by the latency of interrupt processing.
3. 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.
