Internal MMI4832 registers are accessed by first writing the register address to the offset address
0x2 (channel 1) or 0xA (channel 2). After that only the internal register can be read or written to via
the offset address 0x0 (channel 1) or 0x4 (channel 2).
Table 4 contains the bit mapping of MMI4832's internal address register.

Autoincrement addressing mode. The base address of an internal register is written to A(4:2). The
access is repeated n times, where n is the number of words.
