MR: Manual Reset
The RESET output can be forced HIGH externally using
the Manual Reset (MR) input. MR is a de-bounced, TTL
compatible input, and so it may be operated by con-
necting a push-button directly from V
RESET remains HIGH for time t
returned to its LOW state (See Figure 19). An exter-
nal “pull down” resistor is required to hold this pin
(normally) LOW.
