Figure 5.14 Serial Interface Timing Diagram when VCC = 3 V
NOTES:
1. When selecting the digital filter by the INTi
input filter select bit, use the INTi input HIGH width to the greater value, either
(1/digital filter clock frequency x 3) or the minimum value of standard.
2. When selecting the digital filter by the INTi
input filter select bit, use the INTi input LOW width to the greater value, either
(1/digital filter clock frequency x 3) or the minimum value of standard.
