(3) Carry & borrow outputs
Carry output (the pulse width is 25 ns MIN. 120 ns MAX. irrespective of the A/B phase input cycle. Similarly, if the
counter performs a down-count operation when the count value is 00
output.
therefore, when a PD4704 is added, a reset must be executed at the same time.
If the counter performs an up-count operation when the count value is 0FF
A Borrow pulse is also output if a down-count operation is performed while RESET is “H” (during a reset), and
H
, an active-low pulse is output to the Borrow
H
, an active-low pulse is output to the
