6.1 Internal Register
The internal registers of CM6206LX can be divided to two parts. Some of them (REG0, REG1, REG2, REG3,
REG4 and REG5) are 16-bit width and can be accessed via HID interface SET_RPT request. The others
(REG8~ REG14) are 8-bit width and can be accessed by vendor requests.
To access registers via HID interface, users should issue a “Set Output Report” HID request. The four
bytes of output report data is organized as below:
Byte [0]
Byte [1]
Byte [2]
Byte [3]
Bit5 = 1 => Access internal register
Bit4 = 1 => read Bit4 = 0 => write
