The CAN I/O module is implemented as an
AVR Studio plugin. If this plugin is not installed,
AVR Simulator will print an error message "CAN (AVRSimIOCAN00.SimIOCAN00) not supported." This plugin can be downloaded from Atmel's website at
http://www.atmel.com/products/avr/.
When writing to UCSRnC, the value will be copied to UBRRnH unless bit 7 is set. This behaviour should not happen on devices that have separate locations for these registers. A workaround is to write UBRRnH after UCSRnC.
The JTD bit in the MCUCR register must be set to the desired value twice within four cycles to change its value. In the simulator the JTD bit can be written directly.
The ADC noise reduction function is not supported. Setting the ADIF flag will not wake the CPU from sleep mode.
