8.3 Summary of the functions controlled by decoder registers 0 to F
The decoder uses 16 programmable registers, accessible under internal microcontroller control. The addresses of these
registers are given in Table 31, along with a summary of the functions performed. The INITIAL column shows the
power-on reset state.
