This register allows software to access the contents of any one of the eight
internal waveform CODE registers, addressed by the CRA[2:0] bits in the CODE
Indirect Address register. When accessing the internal CODE registers, the
address of the desired register must first be written to the Indirect Address
register (Register 16H).Then, by reading or writing the Indirect Data register, the
microprocessor can either read from or write to the internal register identified by
the CRA[2:0] bits.
The value read from or written to the internal CODE registers is contained in the
CRD[3:0] bits. CRD3 is the most significant bit.
See the Operation section for more details on setting up custom waveform
templates.
