Enumeration
Byte 92, bit 2 indicates whether or not it is necessary for the host to perform an address change sequence before accessing information at 2-wire serial address A2h. If this bit is not set, the host may simply read from either address, A0h or A2h, by using that value in the address byte during the 2-wire communication sequence. If the bit is set, the defined sequence must be executed prior to accessing information at address A2h.
