Note 1:
The accumulator spans registers NCO1ACCU:NCO1ACCH: NCO1ACCL. The 24 bits are reserved but
not all are used.This register updates in real-time, asynchronously to the CPU; there is no provision to
guarantee atomic access to this 24-bit space using an 8-bit bus. Writing to this register while the module is
operating will produce undefined results.
