Terminal Configuration and Functions

NOTE

For more information, see the hysteresis values in Section 5.7, DC Electrical Characteristics.

12. BUFFER TYPE: Drive strength of the associated output buffer.

NOTE

For programmable buffer strength:

–

The default value is given in Table 4-1.

–

A note describes all possible values according to the selected muxmode.

13. PULL UP / DOWN TYPE: Denotes the presence of an internal pullup or pulldown resistor. Pullup and

pulldown resistors can be enabled or disabled via software.

14. DSIS: The deselected input state (DSIS) indicates the state driven on the peripheral input (logic "0" or

logic "1") when the peripheral pin function is not selected by any of the CTRL_CORE_PADx registers.

–

0: Logic 0 driven on the peripheral's input signal port.

–

1: Logic 1 driven on the peripheral's input signal port.

–

blank: Pin state driven on the peripheral's input signal port.

NOTE

Configuring two pins to the same input signal is not supported as it can yield unexpected

results. This can be easily prevented with the proper software configuration (Hi-Z mode is not

an input signal).

NOTE

When a pad is set into a multiplexing mode which is not defined by pin multiplexing, that

pad’s behavior is undefined. This should be avoided.
