Reading or writing multiple bytes from/to single-byte registers increments the register ID along with it. For example reading two bytes from reg 0x00 reads regs 0x00 and 0x01.
 +
 +
This is not the case for multibyte regs (0x29, 0x2D, 0x4F, 0x61 and 0x7F), plus reg 0x60.

Reading from this register seem to read N bytes from the bank while incrementing the internal index by the same amount.

Writing to here seems to increment the internal index?

Accessing N bytes of this register increments the selected index by N.
