SLG46116

7.0 I/O Pins

The SLG46116 has a total of 7 multi-function I/O pins which can function as either a user defined Input or Output, as well as

serving as a special function (such as outputting the voltage reference). Refer to Section 2.0 Pin Description for pin definitions.

Of the 7 user defined I/O pins on the SLG46116, all but one of the pins (Pin 1) can serve as both digital input and digital output.

Pin 1 can only serve as a digital input pin.

7.1 Input Modes

Each I/O pin can be configured as a digital input pin with/without buffered Schmitt trigger, or can also be configured as a low

voltage digital input. Pins 2 and 3 can also be configured to serve as analog inputs to the on-chip comparators.

7.2 Output Modes

Pins 2, 3, 10, 11, 12, and 13 can all be configured as digital output pins.

7.3 Pull Up/Down Resistors

All I/O pins have the option for user selectable resistors connected to the input structure. The selectable values on these resistors

are 10 k

, 100 k and 1 M. In the case of Pin 1, the resistors are fixed to a pull-down configuration. In the case of all other I/O

pins, the internal resistors can be configured as either pull-up or pull-downs.
