Interrupt mapping

The following table shows the interrupts that the example system uses.

Table 4-2 Example system interrupts

Number Name Description
0 UART0_IRQn UART 0 interrupt
1 GPIO0_IRQn GPIO 0 interrupt
2 GPIO1_IRQn GPIO 1 interrupt
3 QSPI0_IRQn Quad Serial Port Interface (QSPI) 0, (Arty board) interrupt
4 DAP_QSPI0_IRQn V2C-DAPLink board QSPI 0 interrupt
5 DAP_SPI0_IRQn V2C-DAPLink board SPI 0 interrupt
6 DAP_QSPI_XIP_IRQn V2C-DAPLink board QSPI eXecute In Place (XIP) interrupt

If you use CMSIS for your software flow, these interrupts are enumerated in the ARTY_CM3.h and startup_ARTY_CM3.s files.


Additionally, IRQ[31] is connected to DAPLINK_fitted_n. This is used as a level-detect non-interrupt signal to determine if the V2C-DAPLink is fitted.
