10 General Purpose I/O

The general purpose I/O pins can be configured to act in three different ways:

• input

• output

• alternate function (internally controlled)

The following GPIO are available on the GM862-QUAD/PY:

32 GPIO8 I/O GPIO08 Configurable GPIO CMOS 2.8V 1uA / 1mA INPUT LOW

34 GPIO9 I/O GPIO09 Configurable GPIO CMOS 2.8V 1uA / 1mA INPUT LOW

38 GPIO10 I/O GPIO10 Configurable GPIO CMOS 2.8V 1uA / 1mA INPUT LOW

40 GPIO11 I/O GPIO11 Configurable GPIO CMOS 2.8V 1uA / 1mA INPUT HIGH HIGH 4.7K Pull Up

42 GPIO12 I/O GPIO12 Configurable GPIO CMOS 2.8V 1uA / 1mA INPUT HIGH HIGH 47K Pull Up

44 GPIO13 I/O GPIO13 Configurable GPIO CMOS 2.8V 1uA / 1mA INPUT LOW

Input pins can only be read and report the digital value (high or low) present on the pin at the read

time; output pins can only be written or queried and set the value of the pin output; an alternate

function pin is internally controlled by the GM862-QUAD/PY firmware and acts depending on the

function implemented.
