(2) Power-on reset
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 reset 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.
Fig 50. Power-on reset operation
Note 1. Output latch is set to “1.”
Note 2. The output structure is N-channel open-drain.
Note 3. Pull-up transistor is turned OFF.
