execution clocks of an instruction increases by the number of wait clocks (for the number of wait clocks, see Table 27-
1). This must be noted when real-time processing is performed.
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
When accessing the peripheral hardware that may cause a conflict, therefore, the CPU repeatedly executes
As a result, the CPU does not start the next instruction processing but waits. If this happens, the number of
