7.10.11 Flash Bank Sector Enable Register (FBSE)
FBSE provides one enable bit per sector for up to 16 sectors per bank. Each bank in the Flash module
has one FBSE register. The bank is selected via the BANK bits in the FMAC register. As only one bank at
a time can be selected by FMAC, only the register for the bank selected appears at this address.
