31.1.14.1 Manual Panel Swap

The memory region order of the BFM (and PFM) panels is entirely the user’s responsibility. The control bit, SWAP.BFSWAP (SWAP.PFSWAP), provides the manual control to swap the order of the panels. In order to properly swap the BFM (or PFM) panel regions, there must not be any accesses to either panel when changing the BFSWAP (PFSWAP) bit. Accesses to regions not being swapped, or SRAM is allowed.

An example device memory map is shown in the following figure with the PFSWAP bit set or cleared.
