other in value. Then, Z
Two measurements give the value of this resistance and the strength of the driver current source. First, the
output voltage is measured while driving logic 1 without an external differential termination resistor. The
measured voltage is V
with an external precision differential termination resistor of value R
V
The drive current is then I

The MPC8343EA power-on configuration options can be set through external pull-up or pull-down
resistors of 4.7 kΩ on certain output pins (see the customer-visible configuration pins). These pins are used
as output only pins in normal operation.
