2.2.4 User Pushbuttons [SW3] [SW5] [SW6] [SW8] [SW15] with User LED Indication [LD2] [LD3]

The pushbutton(s) primary function is to be user/application defined. The inputs can be monitored and/or configured to generate an interrupt. Some pushbutton(s) support a secondary function. They can be used to wake the system from a low power mode. Table 2-9 lists a complete definition for each pushbutton.

Table 2-9 User Pushbuttons and LEDs
Push Button Primary Function Alternate Function
[SW3] User Define (GPIO0_11) Wake from low power mode (MAIN IO_RET)
[SW5] User Define (WKUP_GPIO0_7) Wake from software initiated power-down (OFF)
[SW6] User Define (GPIO0_0) External Interrupt (EXTINTn)
[SW8] User Define (WKUP_GPIO0_70) Wake from low power mode (MCU IO_RET)
[SW15] User Define (PMIC_GPIO4) Wake from low power mode (any LP_STBY).
LED Primary Function Alternate Function
[LD2] User Define (IO_EXP 0x22, bit P26) None
[LD3] User Define (IO_EXP 0x22, bit P27) None
Note: The user-defined pushbutton inputs and LED outputs are connected to processor pins. The pins can be accessed via GPIO functions of the pin. The specific pin/GPIO used is identified in the table.
