Load the PWM counter with a value between 0x0 and 0xFF.
PWM value: (0-255)
Loads an absolute value between 0-255 into PWM count
This instruction loads the Step Number into the instruction counter
Loop Count: (0-63)
Number of loops to repeat. 0 means infinite loop
Addr: (0 or 1)
0 – Absolute addressing
1 – Relative addressing
Step Size: (0-63)
The step number to be loaded to instruction counter
End the instruction execution by resetting and interrupting to the host.
Capable of waiting as well as sending triggers to another PWM channel. Can be
configured to send/receive external trigger
