PIN FUNCTIONS
high when ever there is a transition on the WDI pin, or
LOW LINE goes low. The watchdog timer can be disabled
by floating WDI (see Figure 11).
RESET (Pin 15): Logic output for μP reset control. The
LTC1235 provides three ways to generate μP reset. First,
whenever VCC falls below either the reset voltage threshold
(4.65V, typically) or VBATT, RESET goes active low. After
VCC returns to 5V, the reset pulse generator forces RESET
to remain active low for a minimum of 140ms. Second,
when the watchdog timer is enabled but not serviced
prior to the time-out period, the reset pulse generator
also forces RESET to active low for a minimum of 140ms
for every time-out period (see Figure 11). Third, when the
PB RST pin stays active low for a minimum of 40ms,
RESET is forced low by reset pulse generator. The RESET
signal will remain active low for a minimum of 140ms from
the moment the push-button reset input is released from
logic low level.
RESET (Pin 16):
RESET is an active high logic output. It
is the inverse of RESET.
