Notes 1.

The first clock pulse is generated after this period when the start/restart condition is detected.

The maximum value (MAX.) of tHD:DAT is during normal transfer and a wait state is inserted in the ACK

(acknowledge) timing.

Caution

The values in the above table are applied even when bit 2 (PIOR2) in the peripheral I/O redirection

the redirect destination.

Remark

The maximum value of Cb (communication line capacitance) and the value of Rb (communication line pull-up

resistor) at that time in each mode are as follows.

Fast mode plus: Cb = 120 pF, Rb = 1.1 k
