RESETS AND INTERRUPTS

4.1.3
Illegal Address (ILADR) Reset
The MCU monitors all opcode fetches. If an illegal address space is accessed during an opcode
fetch, an internal reset is generated. Illegal address spaces consist of all unused locations within
the memory map and the I/O registers (see Figure 3-1). Because the internal reset signal is used,
the MCU comes out of an ILADR reset in the same operating mode it was in when the opcode was
fetched.
4.1.4
Computer Operating Properly (COP) Reset
The MCU contains a watchdog timer that automatically times out if not reset (cleared) within a
specific amount of time by a program reset sequence.

NOTES:
1. XTAL is not meant to represent frequency. It is only used to represent time.
2. Internal clock, internal address bus, and internal data bus signals are not available externally.
3. Next rising edge of internal clock after rising edge of RESET initiates reset sequence.
