Outputs Enable Control

In addition to output control via I2C, each GPIO pin can be programmed to be OEx (Output Enable)

for one or for a group of outputs (see Table 3-1). OEx is active high and the output is enabled/

disabled synchronously to offer glitch-free transitions. As shown in the figures below, after the

change in the logic level of the OEx, the output enable/disable will occur after two to four output

clock cycles. The user can enable (default) or disable any output independently through the I2C

interface by setting the corresponding obufx_en register or using dedicated GPIO (see Table 3-1).
