Program Description:
-------------------
This is the generic EFM8 USB Firmware Library. Please see the EFM8 Libraries
Documentation for more information (/doc/EFM8/software/Lib/index.html).
Known Issues and Limitations:
----------------------------
1) The library does not reset its Data Toggle after receiving a SET_INTERFACE
request.
Target and Tool Chain Information:
---------------------------------
Target: EFM8UB1, EFM8UB2, C8051F320/1, C8051F326/7, C8051F34x, C8051F38x
Tool chain: Keil
File List:
---------
/inc/efm8_usb.h
/src/efm8_usbd.c
/src/efm8_usbdch9.c
/src/efm8_usbdep.c
/src/efm8_usbdint.c
Release Information:
-------------------
Version 1.0.0
- Initial release.
Version 1.0.1
- Fixed bug in logic of remote wakeup feature where the device would
attempt to wake the host before enabling its USB transceiver.
- Fixed bug where the device would stall the Data Phase instead of the
Setup Phase when sending a procedural stall on Endpoint 0.
- Fixed bug where a bus-powered device would look at VBUS after a USB Reset
to determine if it should enter the Default or Attached State. VBUS is
always present on a bus-powered device, so it should automatically enter
the Default State.
- Removed code that generated a compiler warning when
USB_PWRSAVE_MODE_FASTWAKE was enabled.
- Improved documentation of USB_PWRSAVE_MODE_FASTWAKE feature.
