Table 5. CLK reverse signal
DELAY [6..0]
Note 1: DELAY [6..0] is fixed at 00H, when CNTSEL is “H” or “open”.
Note 2: This delay value is typical value at Ta = 25 C. And the value varies by the ambient temperature and
Note 1: CKS is “0”, when CNTSEL is “H” or “open.”

delay is 0.2%/ C.
Calculated example:
DATA is sampled on rising edge of CLK.
DATA is sampled on falling edge of CLK.

In case of delay time is 20ns at Ta = 25 C;
(a) In case Ta rising to 50 C.
(b) In case Ta falling to 0 C.
Increase of delay time
So, the total delay time is 21 ns at Ta = 50 C.
Decrease of delay time
So, the total delay time is 19 ns at Ta = 0 C
