NOTE:
When the LVISTOP is enabled, the system stabilization time for power
on reset and long stop recovery (both 4096 CGMXCLK cycles) gives a
delay longer than the enable time for the LVI. There is no period where
the MCU is not protected from a low power condition. However, when
using the short stop recovery configuration option, the 32-CGMXCLK
delay is less than the LVI’s turn-on time and there exists a period in
startup where the LVI is not protecting the MCU.
STOP — STOP Instruction Enable Bit
STOP enables the STOP instruction.
1 = STOP instruction enabled
0 = STOP instruction treated as illegal opcode
COPD — COP Disable Bit
COPD disables the COP module. (See Section 9. Computer
Operating Properly (COP).)
1 = COP module disabled
0 = COP module enabled
