26.5.4.3.2 Procedure for Automatic Page Writes (CTRLB.MANW=0)

The row containing the page to be written must be erased before the last write to the page buffer is performed.

• Write to the page buffer by addressing the NVM main address space directly.

  When the last location in the page buffer is written, the page is automatically written to NVM main address space. (Partial page writes are possible and require writing 0xFF in the remaining bytes of the page buffer)

• INTFLAG.READY will be zero while programming is in progress and access through the AHB will be stalled.
