General Purpose
Input/Ouput
GIO0
GIO00/LED0-GIO3/LED3 34-31 I/O
General purpose input/output pin,
LED driver
GIO1
GIO10/SW10-GIO15/SW15 17-14 I/O
General purpose input/output pin,
36-35
Switch input
GIO16/SW16-GIO17/SW17 3-2
I5V/nD5V General purpose input/output pin,
Switch input
Note: In order to have a Negative Edge Interrupt capability for SW10 - SW17, the
corresponding Switch Inputs should also be connected to the extended resistive network
acting on the _WKUP pin. Switch closure must be tied to Ground; the IC will remain in high
power consumption mode until all the switches are released.
GIO2
