Not all GPIO pins support all these three modes:

• GPIO1 is an INPUT ONLY

• GPIO2 is an OUTPUT ONLY (open collector)

• GPIO3, GPIO8 to GPIO13 support both input or output mode but not Alternate function.

• GPIO4 supports all three modes and can be input, output, RF Transmission Control

(Alternate function)

• GPIO5 supports all three modes and can be input, output, RFTXMON output (Alternate

function)

• GPIO6 supports all three modes and can be input, output, ALARM output (Alternate function)

• GPIO7 supports all three modes and can be input, output, BUZZER output (Alternate

function)

All GPIO pins except from GPIO1 and GPIO2 that are buffered with a transistor, are 2.8V CMOS

signals.
