Changes

|
| 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.
