DescriptionResetTypeNameBit/Field
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

External Code Size
This field selects the size of the external code. If the size of the external
code is larger, a bus fault occurs. If the size of the external peripheral
is smaller, it wraps (upper address bits unused).
Note: When not using byte selects in Host-Bus 16, data is accessed
on 2-byte boundaries. As a result, the available address space
is double the amount shown below.
DescriptionValue
256 bytes; lower address range: 0x00 to 0xFF0x0
64 KB; lower address range: 0x0000 to 0xFFFF0x1

256MB; lower address range: 0x000.0000 to 0x0FFF.FFFF0x3
