Clock Pulses
The Clock Pulses are flags that are turned ON and OFF at regular intervals by the system.
The Clock Pulses are specified with labels (or symbols) rather than addresses.
Note The CX-Programmer treats Clock Pulses as global symbols beginning with P_.
The Clock Pulses are read-only; they cannot be overwritten from instructions or the CX-Programmer.
The Clock Pulses are cleared at the start of operation.
