Member Function Documentation

cpu_ack_irq()

void ArchXT_IntCtrl::cpu_ack_irq ( int_vect_t  vector )

overrideprotectedvirtual

Called by the CPU when it acknowledges a vector, i.e. it is about to execute the vector address in the flash.
The base implementation calls the ACK handler of the vector and raise the signal with the "Acknowledged" state.

Reimplemented from InterruptController.

cpu_reti()

void ArchXT_IntCtrl::cpu_reti ( )

overridevirtual

Called by the CPU when returning from an ISR (executing a RETI instruction).
The base implementation calls update_irq to determine the next vector to be given to the CPU.

Reimplemented from InterruptController.

get_next_irq()

InterruptController::IRQ_t ArchXT_IntCtrl::get_next_irq ( ) const

overrideprotectedvirtual

Abstract method indicating which vector should be executed next. Architecture specific behaviors can be implemented here to take into account priority arbitration between vectors.

Note

implementations should assume the GIE flag is set.

Returns

IRQ to be executed next or NO_INTERRUPT

Implements InterruptController.

init()

bool ArchXT_IntCtrl::init ( Device &  device )

overridevirtual

Virtual method called when the device is initialised. This is where the peripheral can allocate its I/O registers, interrupts or connect signals.

Returns

boolean indicates the success of all allocations.

Reimplemented from Peripheral.

ioreg_write_handler()

void ArchXT_IntCtrl::ioreg_write_handler ( reg_addr_t  addr, const ioreg_write_t &  value  )

overridevirtual

Virtual method called when the CPU is writing a I/O register allocated by this peripheral. The value has already been written.

Parameters

addr	the register address in I/O space
value	the new register content

Reimplemented from Peripheral.
