 Data length of input laser is 4-bit bytes.
 The first byte of instruction code is 0x01.
 The Pin22 signal needs to be turned on 10us in advance before sending Pin2 and
Pin3 signals. After finished pulse width adjustment, Pin2 and Pin3 signals need ≥ 10us
delay before turning off Pin22 signal (as shown in Figure 14).
 All instruction design starts with byte 0xA5.
 Set Pin19 low before using pulse width control function.
 Pulse width control instruction code
Instruction
Set-up pulse width
It takes less than 50ns to finish the fiber laser pulse width initialization.
Remarks: If Instruction code transmit 3 * 0x01 instruction, it will not be accepted by the laser.
 Pulse width time sequence
 The following figure is an example to illustrate the sampling series diagram with a
pulse width of 200ns. The series of 0x01 bytes of instructions is as follows:
Example: 0xa5 → 0x01 → 0x00 → 0xc8
0xa5: for activating pulse width control instruction
0x01: for setting pulse width instruction
0x00 and 0xc8: set the pulse width to 200ns.
