TWR-TWRPI-BD Features
• Enables rapid prototyping and evaluation of sensors, radios and
other peripherals available as Tower plug-ins (TWRPIs)
• Adds up to three additional general-purpose TWRPI modules to the
Freescale Tower System and interfaces them with signals available
on the Tower elevator edge connectors
• Provides access to SPI, I
2
C, and UART communication interfaces
• Each TWRPI socket features:
Independent SPI interfaces, each with two selectable slave
select signals
Independent UART interfaces with optional flow control available
on sockets A and C
Independent selection of GPIO or interrupt functionality
Optional TWRPI ID signals for detection of TWRPI modules
• Selectable I
2
C bus shared between all TWRPI sockets
• All signals can be isolated from the Tower System to avoid any
potential signal conflicts with additional peripheral Tower modules
