Table 2.30

IIC timing (1)-2

(1) Conditions: Middle drive output is selected in the Port Drive Capability bit in the PmnPFS register for the following pins: SDA0_B,

SCL0_B, SDA1_B, SCL1_B, SCL0_C, SDA0_C, SCL0_D, SDA0_D, SCL0_E, SDA0_E, SCL0_F, SDA0_F, SCL1_C, SDA1_C, SCL1_D,

SDA1_D, SCL1_E, SDA1_E.

(2) The following pins do not require setting: SCL0_A, SDA0_A, SCL1_A, SDA1_A.

(3) Use pins that have a letter appended to their names, for instance _A or _B or _C or _D or _E or _F, to indicate group membership. For

the IIC interface, the AC portion of the electrical characteristics is measured for each group.

Note:

tIICcyc: IIC internal reference clock (IICφ) cycle.

Note:

Values in parentheses apply when INCTL.DNFS[3:0] is set to 0011b while the digital filter is enabled with INCTL.DNFE set to 1.

Note:

Must use pins that have a letter appended to their name, for instance _A, _B, to indicate group membership. For the IIC interface,

the AC portion of the electrical characteristics is measured for each group.

Note 1. Only supported for SCL0_A, SDA0_A, SCL1_A, and SDA1_A. Other ports are depend on DC characteristics.

Note 2. Cb indicates the total capacity of the bus line.
