Chapter 1 Device Overview MC9S12XE-Family
Block B1 is divided into two 128K blocks. The XGATE is always mapped to block B1S.
On the 9S12XEG128 the flash is divided into two 64K blocks B0 and B1S, the B1S range extending from
0x78_0000 to 0x78_FFFF, the B0 range extending from 0x7F_0000 to 0x7F_FFFF.
The block B0 is a reduced size 128K block on the 256K derivative. On the larger derivatives B0 is a 256K
block. The block B0 is a reduced size 64K block on the 128K derivative.
