Configurable I/O Ports

A number of programmable bi-directional input/outputs I/O are provided on a number of pads on the board, arranged for a surface mounted pin header that can be soldered on if needed. PIO[0:5] are powered from VDD_PADS.

PIO lines can be configured through software to have either weak or strong pull-ups or pull-downs. All PIO lines are configured as inputs with weak pull-downs at reset. Configuration is done through the settings file MIB uploaded through the host connection at device configuration.

In addition to PIO, the lines can be can be configured as interrupt request lines, wake-up lines from sleep modes, status led drivers with multiple internally generated modes, general I/O pins controlled by the host, Bluetooth co-existence interface or as a kHz sleep clock input.

Debug SPI Interface

A header is provided for the module debug bus for certification RF. Access to internal settings and test modes is available using a CSR compatible SPI adapter and UniTest-software.

For more information, please contact Bluegiga’s technical support.

Bluetooth co-existence

Industry standard 2-wire and 3-wire, as well as Unity-3, Unity-4, Unity-3e co-existence schemes are supported as well as the Unity+ -extension, and the associated signals are available. The PIO pads can be configured for these functions among others. The co-existence parameters are set through the settings file uploaded through the host connection.

A U.FL connector is also present for antenna sharing using the module internal RF switch.
