System Design Information
Figure 35. Driver Impedance Measurement
The value of this resistance and the strength of the driver’s current source can be found by making two
measurements. First, the output voltage is measured while driving logic 1 without an external differential
termination resistor. The measured voltage is V1 = Rsource × Isource. Second, the output voltage is measured
while driving logic 1 with an external precision differential termination resistor of value Rterm. The
measured voltage is V2 = 1/(1/R1 +1/R2)) × Isource. Solving for the output impedance gives Rsource = Rterm
× (V
1/V2 – 1). The drive current is then Isource =V1/Rsource.
Table 54 summarizes the signal impedance targets. The driver impedance are targeted at minimum VDD,
nominal OVDD, 105°C.

Configuration Pin Muxing
The MPC8343E provides the user with power-on configuration options which can be set through the use
of external pull-up or pull-down resistors of 4.7 k
on certain output pins (see customer visible
configuration pins). These pins are generally used as output only pins in normal operation.
While HRESET is asserted however, these pins are treated as inputs. The value presented on these pins
while HRESET is asserted, is latched when HRESET deasserts, at which time the input receiver is disabled
and the I/O circuit takes on its normal function. Careful board layout with stubless connections to these
