If the square wave frequency is set to a nonzero value, the trigger function is similar to its
function for the sine and triangle waves. The PDLE will generate a square wave at the set
frequency, starting with a low-to-high transition 420µs after the trigger pulse is received.
If another trigger pulse is received while the PDLE is generating the square wave, it will
reset and begin generating a square wave 420µs after the new trigger edge. The timing
diagram is shown below.
