(2) Power-on reset (only for H version)
Reset can be automatically performed at power on (power-on reset)
by the built-in power-on reset circuit. When the built-in power-on re-
set circuit is used, set the time for the supply voltage to rise from 0 V
to the minimum voltage of recommended operating conditions to
100 s or less.
If the rising time exceeds 100 s, connect a capacitor between the
RESET pin and Vss at the shortest distance, and input “L” level to
RESET pin until the value of supply voltage reaches the minimum
operating voltage.
(3) System reset instruction (SRST)
By executing the SRST instruction, “L” level is output to RESET pin
and system reset is performed.
