2. RESET/P125 is set in an external reset input after a reset release.
3. Because RESET/P125 is set in the external reset input immediately after release of reset, if a reset
4. If using P120 to input the potential for an external low-voltage detector, connect P120 to the
subsystem clock (XT1, XT2), or to input an external clock for the main system clock (EXCLK) or
subsystem clock (EXCLKS), the X1 oscillation mode, XT1 oscillation mode, or external clock
input mode must be set by using the clock operation mode select register (OSCCTL) (for details,
refer to 5.3 (1) Clock operation mode select register (OSCCTL) and (3) Setting of operation mode
for subsystem clock pin). The reset value of OSCCTL is 00H (all of the P121 to P124 pins are
Input port pins).
signal is generated during low level input, the reset status continues until the input rises to the
