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 00H, an active-low pulse is output to the Borrow output.
when a µ 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 0FFH, an active-low pulse is output to the Carry
A Borrow pulse is also output if a down-count operation is performed while RESET is “H” (during a reset), and therefore,
