NOTES
1 These areas are mapped internal OTPROM if the REMAP bit (CCB2 2) is set and EA e 5V Otherwise they are external
memory
2 Code executed in locations 00000H to 003FFH will be forced external
3 Reserved memory locations must contain 0FFH unless noted
4 Reserved SFR bit locations must be written with 0
5 Refer to 8XC196NT User’s Guide and Quick Reference for SFR descriptions
6 WARNING The contents or functions of reserved memory locations may change with future revisions of the device
Therefore a program that relies on one or more of these locations may not function properly
7 The 8XC196NT internally uses 24 bit address but only 20 address lines are bonded out allowing 1 Mbyte external
address space
