Operation:
The STOP instruction stops the both the CPU clock and system clock and causes the
microcontroller to enter Stop mode. During Stop mode, the contents of on-chip CPU registers,
peripheral registers, and I/O port control and data registers are retained. Stop mode can be
released by an external reset operation or by external interrupts. For the reset operation, the
RESET pin must be held to Low level until the required oscillation stabilization interval has
elapsed.
