TS-7970 Silabs Changelog

From embeddedTS Manuals
Revision Changes
0
  • Initial Release
1
  • Added Sleep mode
  • Blinks blue LED in low power modes. Sleep mode does this, as well as USB device connected with no power on the main VIN.
2
  • Added support for REV D boards. Earlier boards will continue to use REV 1 only.
3
  • Fixed Silabs not responding on I2C after sleep mode is used.
4
  • This revision prevents USB suspend from putting the silabs into a low power state. In previous versions if a USB cable is connected, but the serial console is not open, then some operating systems will issue a USB suspend. This would prevent communication over the I2C to the silabs.
