Integrated circuit having a Microcontroller Unit and Methods of Operation therefore. An integrated circuit comprises a microcontroller unit with synchronous logic operably coupled to non-clocked intelligent logic. The non-clocked intelligent logic is arranged to autonomously monitor multiple events associated with an operation of the synchronous logic and, in response thereto, the non-clocked intelligent logic initiates autonomously an alternate operational mode of the microcontroller unit. A method of operating a microcontroller unit is also described.

摘要:
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.

An I/O cell comprising a first set of driver stages comprising, each driver stage of the first set comprising a high side switch controllable to couple an I/O node of the I/O cell to a first high voltage supply node and a low side switch controllable to couple the I/O node of the I/O cell to a first low voltage supply node. The I/O cell further comprising a second set of driver stages, each driver stage of the second set comprising a high side switch controllable to couple the I/O node of the I/O cell to a second high voltage supply node and a low side switch controllable to couple the I/O node of the I/O cell to a second low voltage supply node. The switches of the first set of driver stages are controllable independently of the switches of the second set of driver stages.
摘要:
A method of controlling direct memory access of a peripheral memory of a peripheral by a master is described. The method includes checking whether there is a pending request from the peripheral for a direct memory access service, establishing whether an access condition is satisfied in dependence on at least whether there is a pending request, and, if the access condition is satisfied, granting access to the master. Also, an associated device and an associated computer program product are described.

A microprocessor device comprises at least one reset management module. The at least one reset management module is arranged to detect a reset event comprising a first reset level, determine if at least one reset condition has been met upon detection of the reset event comprising the first reset level, and cause a reset of a second reset level upon determining that the at least one reset condition has been met.
