Digital Input—
Digital Output— A pin that is driven by the device and
Digital Inout—
Description
A pin that is used by the digital but is nev-
er driven.
should not be driven by another device to
avoid contention.
A pin that is either open drain (I2C_SDA)
or a bidirectional CMOS in/out. In the later
case the direction is selected by a control
register within the LM49370.
