This register allows software to select any one of the eight internal waveform
CODE registers, addressed by the CRA[2:0] bits, for subsequent access through
the CODE Indirect Data register. When accessing the internal CODE registers,
the address of the desired register must first be written to this register.Then, by
reading or writing the Indirect Data register (Register 17H), the microprocessor
can either read from or write to the internal register identified by the CRA[2:0]
bits.
The CRA[2:0] bits address the internal registers as follows:
