5.5.2.5 COP Register
The COP register is shared with the LSB of an unimplemented user
interrupt vector as shown in Figure 5-3. Reading this location returns
whatever user data has been programmed at this location. Writing a zero
to the COPR bit in this location clears the COP watchdog timer.
5.5.3 Illegal Address
An illegal address reset is generated when the CPU attempts to fetch an
instruction from I/O address space ($0000 to $001F).
Address:
$3FF0
