Pulse Outputs Section 7-6
7-6-5 Applicable Instructions
The following seven instructions can be used to control pulse outputs. The
relationship between the instruction and the types of pulse output that is pos-
sible is also listed in the following table.
Instructions Ineffective
during Pulse Output
Once pulse output has been started by an instruction, the output cannot
always be changed with an instruction. Refer to 7-6-15 Pulse Output Starting
Conditions for details on the allowed combinations of pulse output instruc-
tions.
