FADDR — 16-bit
Address Register
FADDRHI and FADDRLO are the Flash address registers. These
registers are banked.

Read: Only in the flash super user mode. In user modes, the FADDR
(FADDRHI, FADDRLO) register reads zeros.
Write: Only in the flash super user mode.
For sector erase, the MCU address bits AB[8:0] are don’t care.
For mass erase, any address within the block is valid to start the
command.
AB[15:1] — 64K byte Relative Address of Flash Array
These address bits are used in the program/erase sequence in the
flash super user mode. Refer to Low Power Options in page 229 for
the program/erase sequence.
The mapping of the address information in the FADDR register to the
Flash relative address is shown in Figure 26.
