2.4.4 User Pushbuttons

The pushbuttons primary function is to be user and application defined. The inputs can be monitored and configured to generate an interrupt. Some pushbuttons support a secondary function. Some pushbuttons can be used to wake the system from a low power mode. The table below lists a complete definition for each pushbutton.

Table 2-7 User Pushbuttons and LEDs
Push ButtonPrimary FunctionAlternate Function
[SW3]User Defined (GPIO0_11)Wake from low power mode (MAIN IO_RET)
[SW5]User Defined (WKUP_GPIO0_7)Wake from software initiated power-down (OFF)
[SW6]User Defined (GPIO0_0)External Interrupt (EXTINTn)
[SW8]User Defined (WKUP_GPIO0_70)Wake from low power mode (MCU IO_RET)
[SW15]User Defined (PMIC_GPIO4)Wake from low power mode (any LP_STBY).
LEDPrimary FunctionAlternate Function
[LD2]User Defined (IO_EXP 0x22, bit P26)None
[LD3]User Defined (IO_EXP 0x22, bit P27)None
Note: The user-defined pushbutton inputs and LED outputs are connected to processor pins and/or IO expanders. The pins can be accessed via GPIO functions of the pin or controlled via I2C commands. The specific pin/GPIO used is identified in the table.
