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
the large value of the pull-up/pull-down resistor should minimize the disruption of signal quality or speed
for the output pins.

The MPC8347EA requires high resistance pull-up resistors (10 kΩ is recommended) on open-drain pins,
including I
