60 / 282 page

• Yes: With hysteresis

• No: Without hysteresis

An empty box means No.

For more information, see the hysteresis values in Section 7.6, Electrical Characteristics.

11. BUFFER TYPE: This column describes the associated output buffer type

An empty box means Not Applicable.

For drive strength of the associated output buffer, refer to Section 7.6, Electrical Characteristics.

12. PULL UP/DOWN TYPE: indicates the presence of an internal pullup or pulldown resistor. Pullup and pulldown resistors can be enabled or disabled

via software.

• PU: Internal pullup

• PD: Internal pulldown

• PU/PD: Internal pullup and pulldown

• An empty box means No pull.

13. DSIS: The deselected input state (DSIS) indicates the state driven on the peripheral input (logic "0", logic "1", or "PIN" level) when the peripheral pin

function is not selected by any of the PINCNTLx registers.

• 0: Logic 0 driven on the input signal port of the peripheral.

• 1: Logic 1 driven on the input signal port of the peripheral.

• An empty box means Not Applicable.

14. RXACTIVE / TXDISABLE:This column indicates the default value of the RXACTIVE / TXDISABLE bits in the PADCONFIG register.

• RXACTIVE: 0 = receiver disabled, 1 = receiver enabled.

• TXDISABLE: 0 = driver enabled, 1 = driver disabled.

• An empty box means Not Applicable.

15. IO Daisy Chain:This column indicates which pins can be included in the daisy chain during low power modes.

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 (HiZ 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.
