MMA7660FC internal registers because the register address generally auto-increments.
Message Format for Reading MMA7660FC
is used as address pointer for a write. The pointer generally auto-increments after each data byte is read using the same rules
as for a write. Thus, a read is initiated by first configuring the device’s register address by performing a write
by a repeated start. The Master Write address is 1001 1001 (0x99). The master can now read 'n' consecutive bytes from it, with
the first data byte being read from the register addressed by the initialized register address.
