GENERAL PURPOSE I/O CONTROL

As previously noted, the ADIS16201 provides two general-

purpose, bidirectional I/O pins (GPIOs) that are available to the

user for control of auxiliary circuits within the target application.

All I/O pins are 5 V tolerant, meaning that the GPIOs support

an input voltage of 5 V. All GPIO pins have an internal pull-up

resistor of approximately 100 kΩ, and their drive capability is

1.6 mA. The direction, as well as the logic level, can be

controlled for these GPIO pins through the GPIO_CTRL

control register, as defined in Table 31.

These same GPIO pins are also controllable through the

ALM_CTRL and MSC_CTRL control registers. The priority for

these three control registers in controlling the two GPIO pins is

MSC_CTRL has precedence over ALM_CTRL, which has

precedence over GPIO_CTRL.
