Instruction

Description

LOAD

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

Go to Start (GTS) Branch to the address 0x0 and execute from 0x0 and onwards.

BRANCH

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

End the instruction execution by resetting and interrupting to the host.

Trigger (TRIG)

Capable of waiting as well as sending triggers to another PWM channel. Can be

configured to send/receive external trigger
