Function Documentation

◆ global_trap_handler()

void global_trap_handler ( void )

Trap handler for ALL exceptions/interrupts.

◆ hw_breakpoint_handler()

void hw_breakpoint_handler ( void )

Hardware-breakpoint trap handler

◆ main()

int main ( void )

High-level CPU/processor test program.

Warning: This test is intended for simulation only.; This test requires all optional extensions/modules to be enabled.

Returns: 0 if execution was successful

◆ rte_service_handler()

void rte_service_handler ( void )

RTE's ecall "system service handler"; modifies application context to provide "system services"

◆ sim_irq_trigger()

void sim_irq_trigger ( uint32_t sel )

Simulation-based function to set/clear CPU interrupts (MSI, MEI).

Parameters

[in] sel IRQ select mask (bit positions according to NEORV32_CSR_MIE_enum).

◆ test_fail()

void test_fail ( void )

Test results helper function: Shows "[FAIL]" and increments global cnt_fail

◆ test_ok()

void test_ok ( void )

Test results helper function: Shows "[ok]" and increments global cnt_ok

◆ trigger_module_dummy()

void trigger_module_dummy ( void )

Test function for the trigger module

◆ vectored_global_handler()

void vectored_global_handler ( void )

Vectored trap handler for ALL exceptions/interrupts.

◆ vectored_irq_table()

void vectored_irq_table ( void )

Vectored mtvec mode jump table.

◆ vectored_mei_handler()

void vectored_mei_handler ( void )

Machine external interrupt handler.

◆ xirq_trap_handler0()

void xirq_trap_handler0 ( void )

XIRQ handler channel 0.

◆ xirq_trap_handler1()

void xirq_trap_handler1 ( void )

XIRQ handler channel 1.
