Reset By Reset Pin - Toshiba TX03 Series Manual

5.1.2

Reset by RESET pin

The reset using the RESET pin will be effective after the power-on counter finishes. And if RESET pin is
set to " High " within tPWUP after power-on reset signal becomes " High " , the reset process will be the
same as the power-on described in 5.1.1.
TMPM3V6/3V4 has a function to enable low voltage detection circuit (VLTD) operation. Before RESET
pin is set to " High " , if the supply voltage becomes upper than the detection voltage <VDLVL[1:0]>, inter-
nal reset signal is released after RESET pin is set to " Low " .

If an external reset is generated ahead of this timing,
a reset process will be the same as the internal power-on-reset.
