8.0 AL250/251 Register Definition
The AL250/251 is powered up to a default state depending on the hardware mode-setting pins.
Hardware configuration pins are disabled by setting SoftConfig (bit 4 of register 03h) to one, and
configurations are decided by the values of register 02h which is software programmable.
The following is the summary of the AL250/251 control registers
