Footnote:
1. SENtral’s I 2 C Host Interface supports Standard, Fast, Fast Plus, and High Speed Modes.
High Speed Mode (3400 kHz) is supported with a reduced range of V
DD
and bus
capacitance. SENtral’s I 2
C sensor bus interface supports Standard, Fast, and Fast Plus
Modes. Pass-Through state, which connects the sensor bus and host bus, supports
Standard and Fast Modes.
