Note 4-8-1: These specifications are theoretical values. Add margin depending on its use.
Note 4-8-2: The value of Tfilt is determined by the values of the register SMIC0BRG, bits 7 and 6 (BRP1,
BRP0) and the system clock frequency.

Set bits (BPR1, BPR0) so that the value of Tfilt falls between the following range:
250 ns ≥ Tfilt > 140 ns
Note 4-8-3: Cb represents the total loads (in pF) connected to the bus pins. Cb  400 pF
Note 4-8-4: The standard clock mode refers to a mode that is entered by configuring SMIC0BRG as follows:
250 ns ≥ Tfilt > 140 ns
BRDQ (bit5) = 1
SCL frequency setting  100 kHz
The high-speed clock mode refers to a mode that is entered by configuring SMIC0BRG as follows:
250 ns ≥ Tfilt > 140 ns
BRDQ (bit5) = 0
SCL frequency setting  400 kHz
