The configuration register is used to control the behavior of the corresponding devices. To
configure the register, using the index port to select the index and then writing data port to alter
the parameters. The default index port and data port are 0x4E and 0x4F respectively. Pull down
the SOUT1 pin to change the default value to 0x2E/0x2F. To enable configuration, the entry key
0x87 must be written to the index port. To disable configuration, write exit key 0xAA to the index
port. Following is a example to enable configuration and disable configuration by using debug.
-o 4e 87
-o 4e 87
(enable configuration)
-o 4e aa
(disable configuration)
The Following is a register map (total devices) grouped in hexadecimal address order, which shows
