See Table 2. 2. The 48 kB Flash option (MM912G634) using the same S12I64 MCU with the tested FLASHSIZE reduced to 48 kB. This limits the usable Flash area to the first 48 kB (0x3 4000-0x3 FFFF). 3. The 48 kB Flash option (MM912G634) using the same S12I64 MCU with the tested Data - FLASHSIZE reduced to 2.0 kB. This limits the usable Data Flash area to the first 2.0 kB (0x0 4400-0x0 4BFF). 4. The 48 kB Flash option (MM912G634) using the same S12I64 MCU with the tested RAMSIZE reduced to 2.0 kB. This limits the usable RAM area to the first 2.0 kB (0x0 2800-0x0 2FFF). (5) Table 2.
