IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-k
IPD or IPU resistor. To pull up a signal to the opposite
supply rail, a 1-k
resistor should be used.)

It is recommended that external connections be provided to device configuration pins, including
TOUT1/LENDIAN, AEA[22:19], TOUT0/HPI_EN, CLKINSEL, and OSC_DIS. Although internal
pullup/pulldown resistors exist on these pins, providing external connectivity adds convenience to the user
in debugging and flexibility in switching operating modes.
Internal pullup/pulldown resistors also exist on the non-configuration pins on the AEA bus (AEA[18:3]). Do
not
oppose the internal pullup/pulldown resistors on these non-configuration pins with external pullup/pulldown
resistors. If an external controller provides signals to these non-configuration pins, these signals must be
driven to the default state of the pins at reset, or not be driven at all.
For the internal pullup/pulldown resistors for all device pins, see the terminal functions table.
