Register Map Summary
Control the MSL1061/64 through an I 2 C interface using nine registers (Table 6). The power-up defaults (Table 7) are such
that an MSL1061/64 operates as a standalone LED driver if the I 2 C interface is not used.
The Internal register addressing auto-increments through the register map allowing sequential reads or writes without
needing to write separate addresses for each byte.
