A method of controlling access by a master to a peripheral includes receiving an interrupt priority level from an interrupt controller associated with the peripheral, comparing the interrupt priority level with respective a pre-established interrupt access level to obtain an interrupt level comparison result, establishing whether an access condition is satisfied in dependence on the interrupt level comparison result, and if the access condition is satisfied, granting access. If the access condition is not satisfied, access is denied. Further, a circuitry is described including a master, a peripheral, and an access control circuitry including an interrupt controller associated with the peripheral. The access control circuitry is arranged to perform a method of controlling access by the master to the peripheral.
