5.2.31 Set period of Port D3
0xFF
0xAA
0x19
D3PWMTL
D3PWMTH
D3PWMTL：PWM period of Port D3 low byte
D3PWMTH：PWM period of Port D3 high byte
D3PWMT = (D3PWMTH<<8) | D3PWMTL
Note: The unit of PWM high-level width and period is us, such as high-level
width is 1500us, just set D0PWMH 1500.Period is 20000us, just set D0PWMT
20000.
5.2.32 Set IIC Address
0xFF
0xAA
0x1a
IICADDR
0x00
IICADDR：
IIC address of the module, default is 0x50. IIC address using 7bit address,
can not exceed the maximum 0x7f. After the setup is complete , need to click
save, and re-power the module to take effect.
5.2.33 LED
0xFF
0xAA
0x1b
LEDOFF
0x00
LEDOFF：
0x01：Turn off LED
0x00：Turn on LED
