Power-on reset
The M41T94 continuously monitors V
the RST pulls low (open drain) and remains low on power-up for t
(max). The RST pin is an open drain output and an appropriate pull-up resistor should be
chosen to control rise time.
Reset inputs (RSTIN1 & RSTIN2)
The M41T94 provides two independent inputs which can generate an output reset. The
duration and function of these resets is identical to a reset generated by a power cycle.
