4.3.4.6 Flash Bank Select Register

The Flash bank select register is used to select the appropriate Flash bank. As 8-bit

wide Flash memory may only be accessed through a 512 kB window; this is the only

way to address a larger size Flash memory. Using bits FB0..FB3, 16 Flash banks can be

selected (16x512 kB = 8 MB). The default value on startup of the VMP1 is 0x00.
