Note 4-6-1: These specifications are theoretical values. Add margin depending on its use.
Note 4-6-2: 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:
250ns ≥ Tfilt >140ns
Note 4-6-3: Cb represents the total loads (in pF) connected to the bus pins. Cb ≤ 100pF
Note 4-6-4: The standard clock mode refers to a mode that is entered by configuring SMIC0BRG as follows:
250ns ≥ Tfilt >140ns
BRDQ (bit5) = 1
SCL frequency setting ≤ 100kHz
The high-speed clock mode refers to a mode that is entered by configuring SMIC0BRG as follows:
250ns ≥ Tfilt >140ns
BRDQ (bit5) = 0
SCL frequency setting ≤ 400kHz
