Values of Pull-Up and Pull-Down Resisters
Care must be taken when selecting the values of the pull-up and pull-down resisters used for ports A, B, C
and D and shared pins (PD7 - 0 and TXD):
Higher resistance values result in longer stabilization time for the transition from the active state to the
high-impedance state. Shorter stabilization time follows from use of less resistance. However, lower
resistance allows a higher output current in the drive state and wastes output current, limiting the
necessary load current.
As a guideline, a 10 kΩ resister can typically be used; If shorter transition time from the active state to the
high-impedance state is needed, use 4.7 kΩ.
