Two common boot mode settings are documented below. For a complete definition and list of all supported
modes, see the TDA4VE-Q1/TDA4VL-Q1/TDA4AL-Q1 Technical Reference Manual (TRM).
No Boot: The processor will not attempt to boot any software. This is often selected when downloading software
using an emulator.
SW9 [8:1] = 0000 1110
SW8[8:1] = 0001 0001
SD Card Boot: The processor will attempt to boot from image on SD Card.
SW9[8:1] = 0000 0000 (Default)
SW8 [8:1] = 0100 0001 (Default)
The Dip Switch boot tables are formatted to align with how the settings are documented in the TRM.

2.3.3 Reset Pushbuttons [SW7_CP] [SW6_CP] [SW5_CP] [SW4_CP]
When pressed, the specific EVM domain is issued a reset, and is held in reset until the button is released.

Push Button Domain Function Description
[SW7] All Power-On Reset
Power-On/Cold Reset for EVM,
resets both processor domains
(MCU, MAIN) and all EVM
peripherals.

2.3.4 User Pushbuttons [SW2] [SW11] [SW10] [SW1] [SW12] with User LED Indication [LD9] [LD8]
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.
