NCOxACC

NCO Accumulator Register

Notes:
  1. 1.The individual bytes in this multibyte register can be accessed with the following register names:
    • NCOxACCU: Accesses the upper byte ACC[23:16]
    • NCOxACCH: Accesses the high byte ACC[15:8]
    • NCOxACCL: Accesses the low byte ACC[7:0].
  2. 2.The accumulator spans registers NCOxACCU:NCOxACCH:NCOxACCL. 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 ensure 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.
