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.
