1. Number of 16K pages addressable via PPAGE register
2. Number of 4K pages addressing the RAM. RAM can also be mapped to 0x4000 - 0x7FFF
3. Number of 1K pages addressing the Cache RAM via the EPAGE register counting downwards from 0xFF
4. Number of 1K pages addressing the Data flash via the EPAGE register starting upwards from 0x00
5. The 384K memory map is split into a 128K block from 0x78_0000 to 0x79_FFFF and a 256K block from
6. The 9S12XEA devices are a special bondout for access to extra ADC channels in 80QFP.
7. The 256K memory map is split into a 128K block from 0x78_0000 to 0x79_FFFF and a 128K block from
8. The 128K memory map is split into a 64K block from 0x78_0000 to 0x78_FFFF and a 64K block from
