The ROM includes Reset vector, Interrupt vector, General purpose area and Reserved area. The Reset vector is
program beginning address. The Interrupt vector is the head of interrupt service routine when any interrupt occurring.
The General purpose area is main program area including main loop, sub-routines and data table.
0x0000 Reset Vector: Program counter points to 0x0000 after any reset events (power on reset, reset pin
reset, watchdog reset, LVD reset…).
0x0001~0x0007: General purpose area to process system reset operation.
0x0008~0x0014: Multi interrupt vector area. Each of interrupt events has a unique interrupt vector.
0x0015~0x177F: General purpose area for user program and ISP (EEPROM function).
0x1780~0x17F7: General purpose area for user program. Do not execute ISP.
0x17F8~0x17FF: Reserved area. Do not execute ISP.
ROM security rule is even address ROM data protected and outputs 0x0000.
