SMBus Address
The MK1493-14 is a slave-only device that supports block read and block write protocol using a single 7 bit address and
read/write bit. A block write (D2h) or block read (D3h) is made up of seven (7) bits and one (1) read/write bit.
In applications where the indexed block write and block read
are used, the dummy byte (bit 11-18) functions as a
register-offset (8 bits) pointer.
