2.3.2 Boot Configuration Settings [SW9_CP] [SW8_CP]

Dip switches [SW8] [SW9] are used to configure different boot options available on the processor.

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.
