Preliminary data sheet
6.17 Input/Output Configuration module (IOCONFIG)
6.18 10-bit Analog-to-Digital Converter (ADC10B)
The General Purpose Input/Output (GPIO) pins can be controlled through the register
interface provided by the IOCONFIG module. Next to several dedicated GPIO pins, most
digital IO pins can also be used as GPIO if they are not required for their normal,
dedicated function.
This module has the following features:
This module is a 10-bit successive approximation ADC with an input multiplexer to allow
for multiple analog signals on its input. A common use of this module is to read out
multiple keys on one input from a resistor network.
This module has the following features:

After a reset, a register will indicate whether a reset has occurred because of a
watchdog generated reset.
Watchdog timer can also be used as a normal timer in addition to the watchdog
functionality (output m0).
Provides control for the digital pins that can double as GPIO (next to their normal
function). The pinning list in
Each controlled pin can be configured for 4 operational modes:
– Normal operation (i.e. controlled by a function block)
– Driven LOW
– Driven HIGH
– High impedance/input
A GPIO pin can be observed (read) in any mode.
The register interface provides ‘set’ and ‘clear’ access methods for choosing the
operational mode.
Four analog input channels, selected by an analog multiplexer.
Programmable ADC resolution from 2 bit to 10 bit.
The maximum conversion rate is 400 kSamples/s for 10 bit resolution and
1500 kSamples/s for 2 bit resolution.
Single and continuous analog-to-digital conversion scan modes.
Power-down mode.
