Freescale Semiconductor
System Design Information
output impedance is the average of two components, the resistances of the pull-up and pull-down devices.
When data is held high, SW1 is closed (SW2 is open) and RP is trimmed until the voltage at the pad equals
OVDD/2. RP then becomes the resistance of the pull-up devices. RP and RN are designed to be close to each
other in value. Then, Z0 = (RP + RN)/2.
Figure 45. 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 × (V1/V2 – 1). The drive current is then Isource =V1/Rsource.
Table 65 summarizes the signal impedance targets. The driver impedance are targeted at minimum VDD,
nominal OVDD, 105°C.

Configuration Pin Multiplexing
The MPC8323E 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
Ω on certain output pins (see customer visible
configuration pins). These pins are generally used as output only pins in normal operation.
