6. IO Local GPIO Interface
For the development of small IO-Devices the TPS-1 offers the IO Parallel Interface with a maximum of 48 IO lines. These lines could be used for input,
output and diagnostic purposes.
There are some restrictions when using the IO Local Parallel interface.
• You can have only one Application Identifier (API).
• It is only one module (slot) possible.
• It is only one submodule (subslot) possible.
• The input, output and diagnostic bits must be in a connected order.
• You must always choose groups in byte range (8, 16, 24, 32, etc.).
The TPS Configurator supports the configuration of the IO Local Parallel Interface. (Refer Appendix. A “Configuration of the IO Local Parallel
Interface”)
6.1. GPIO (digital input and output)
The I/O interface supports 48 GPIOs (General Purpose Inputs/Outputs). The GPIOs can be used for digital IOs. Each pin can be used individually or in
combination with other pins.
Parallel use of the GPIOs and the host interface is not possible!
Unused GPIO pins should be pulled up (10 kΩ to Vcc33).
From stack version 1.4, the following applies:
Unused GPIO pins should be left open. After start up the unused signal lines are switched to outputs.
