12. RESET FUNCTION
When a low-level signal is input to the RESET pin, the system is reset, and each hardware unit is initialized (reset).
During the reset period, oscillation of the main system clock is unconditionally stopped. Consequently, the current
consumption of the entire system can be reduced.
When the RESET signal goes high, the reset status is cleared, the oscillation stabilization time (84.0 ms at 12.5
MHz operation) elapses, the contents of the reset vector table are set to the program counter (PC), execution
branches to an address set to the PC, and program execution is started from that branch address. Therefore, the
program can be reset and started from any address.
