1. Calculated according to the BCLK frequency as follows:
2. Calculated according to the BCLK frequency as follows:
3. This standard value shows the timing when the output is off, and
= V
does not show hold time of data bus.
Hold time of data bus varies with capacitor volume and pull-up
(pull-down) resistance value.
Hold time of data bus is expressed in
by a circuit of the right figure.
For example, when V
