7.7. GPIO Configuration
Three general purpose IOs (GPIOs) are available. Numerous functions such as specific interrupts, TRSW control,
Microcontroller Output, etc. can be routed to the GPIO pins as shown in the tables below. When in Shutdown mode
all the GPIO pads are pulled low.
Note: The ADC should not be selected as an input to the GPIO in Standby or Sleep Modes and will cause excess current con-
The GPIO settings for GPIO1 and GPIO2 are the same as for GPIO0 with the exception of the 00000 default
setting. The default settings for each GPIO are listed below:
For a complete list of the available GPIO's see “AN466: Si4430/31/32 Register Descriptions.”
The GPIO drive strength may be adjusted with the gpioXdrv[1:0] bits. Setting a higher value will increase the drive
strength and current capability of the GPIO by changing the driver size. Special care should be taken in setting the
drive strength and loading on GPIO2 when the microcontroller clock is used. Excess loading or inadequate drive
may contribute to increased spurious emissions.
