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
drive current is then I

The MPC8347E 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.
However, while HRESET is asserted, these pins are treated as inputs, and the value on these pins is latched
when PORESET deasserts. Then the input receiver is disabled and the I/O circuit takes on its normal
function. Careful board layout with stubless connections to these pull-up/pull-down resistors coupled with
