This product has two internal system buses.
One is a CPU bus and the other is a peripheral bus that interfaces with the low-speed peripheral hardware.
Because the clock of the CPU bus and the clock of the peripheral bus are asynchronous, unexpected illegal data may
When accessing the peripheral hardware that may cause a conflict, therefore, the CPU repeatedly executes processing,
As a result, the CPU does not start the next instruction processing but waits. If this happens, the number of execution
