lisigrokdecode has recently gained support for yet another protocol decoder: sda2506.
This PD decodes the Siemens SDA 2506-5 serial nonvolatile 1-Kbit EEPROM protocol.
This is a non-standard EEPROM (i.e., not one of the common I²C based 24xx series EEPROMs).
As usual there are a few example files in the sigrok-dumps repo and some test-cases in sigrok-test.
The decoder was contributed by Max Weller, thanks a lot!
