DLATCH Primitive
The DLATCH
primitive.
Note: When the
CLRN
input is low, the latch is reset to low. When the
PRN
input is low, the latch is reset to high. If neither
CLRN
nor PRN
is low, the latch output depends on
the value of the ENA
(latch-enable) input. If the ENA
input is high, the latch passes a signal from the D
input to the
Q
output, else the state of Q
is maintained,
regardless of the D
input.
