• Description: Hcs12 Microcontrollers 16-bit Automotive Microcontroller
• Manufacturer: Freescale Semiconductor, Inc

fault information will be recorded until the specific ECC fault flag has been cleared. In the event of
simultaneous ECC faults the priority for fault recording is double bit fault over single bit fault.
All FECCR bits are readable but not writable.

ECC Parity Bits — Contains the 8 parity bits from the 72 bit wide P-Flash data word or the 6 parity bits,
allocated to PAR[5:0], from the 22 bit wide D-Flash word with PAR[7:6]=00.
Global Address — The GADDR[22:16] field contains the upper seven bits of the global address having
caused the error.
