Simplified I2C mode serial transfer timing (during communication at same potential)

Remark 1.

Rb[

Ω]: Communication line (SDAr) pull-up resistance, Cb[F]: Communication line (SDAr, SCLr) load capacitance

Remark 2.

r: IIC number (r = 00, 01, 10, 11, 20, 21, 30, 31), g: PIM number (g = 0, 1, 3 to 5, 14),

h: POM number (h = 0, 1, 3 to 5, 7, 14)

Remark 3.

fMCK: Serial array unit operation clock frequency

(Operation clock to be set by the CKSmn bit of serial mode register mn (SMRmn). m: Unit number (m = 0, 1),

n: Channel number (n = 0 to 3), mn = 00 to 03, 10 to 13)
