MR
I ST (1) Manual Reset input pin
This input allows a push button switch to be
directly connected to the
TC1270A/70AN/71A’s MR pin, which can then
be used to force a system Reset. The input fil-
ter (ignores) noise pulses that occur on the
MR pin.
H = Switch is open (internal pull-up resistor
pulls signal high). State of the RST/RST
pin determined by other system condi-
tions.
L = Switch is depressed (shorted to ground).
This forces the RST/RST pin Active.
