Atmel XMEGA-A1 Xplained Evaluation Board ATAVRXPLAIN ATAVRXPLAIN データシート

 

8370C-AVR-12/11 

programming is performed through the FLIP plug-in in AVR Studio (which can also be 
started as a standalone application). 

Alternatively, the AT32UC3B1256 can be programmed by connecting a programming 
tool, such as JTAGICE mkII, to test points TP600-607. 

NOTE 

It is not recommended to program the AT32UC3B1256 using a programming tool, as 
this will erase the boot loader. 

The XMEGA analog PORTA is available on the J2 header. This allows the user to 
connect external signals to the analog-to-digital converter (ADC), digital-to-analog 
converter (DAC), and analog comparators on PORTA. 

The XMEGA digital PORTF and PORTC are available on the J1 and J4 headers, 
respectively. These ports feature general-purpose I/O and various communication 
modules (USART, SPI, and TWI). PORTD and PORTF are mixed on the J3 header. 

NOTE 

The communication modules on PORTC and PORTF can be interconnected to test 
various functions and features: The USART can loop back communication with a 
jumper, or communicate between the two USARTs on the port. The native SPI and 
the USART in SPI master mode can be connected, and the TWI module can be 
enabled in both master and slave modes at the same time to get loop-back behavior. 
(Pull-up resistors can be mounted on R101 and R102. These are not mounted from 
the factory.)
