* Firmware for an AVRStudio compatible AVRISP-MKII clone programmer. This project will enable the USB AVR series of
* microcontrollers to act as a clone of the official Atmel AVRISP-MKII programmer, usable within AVRStudio. In its
* drivers. When prompted, direct your OS to install Atmel's AVRISP-MKII drivers provided with AVRStudio.
*
* Note that this design currently has the following limitations:
- * - Minimum ISP target clock speed of 500KHz due to hardware SPI module prescaler limitations
* - No reversed/shorted target connector detection and notification
- * - A seperate header is required for each of the ISP, PDI and TPI programming protocols that the user wishes to use
+ * - A separate header is required for each of the ISP, PDI and TPI programming protocols that the user wishes to use
*
* On AVR models with an ADC converter, AVCC should be tied to 5V (e.g. VBUS) and the VTARGET_ADC_CHANNEL token should be
* set to an appropriate ADC channel number in the project makefile for VTARGET detection to operate correctly. On models
