Figure 3-11 Flash 8-bit Address Low Register (FADDRLO)
In user modes, the FADDR (FADDRHI, FADDRLO) register reads zeros and is not writable. The unused
bits in register FADDRHI (gray shaded bit positions in Figure 3-10) read zero and are not writable.
The FADDRHI and FADDRLO registers can be written in special modes by writing to address BASE +
$108 and BASE + $109 in the register space.
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.
