Table 2
UNUSED INPUTS
Input or bidirectional pins must have a suitable pullup or pulldown reststor if they are configured as inputs, with no external drive. Some
inputs have an internal pullup or pulldown resistor of the order of 100k
; this value is suitable if the pin is not subject to excessive noise
or residual current greater than 15
μ
A. If the pins shown in Table 2 are not used in the system, an external resistor will be required.
