Notes: 1. Standard pin-out for JTAGICE mkII and other Atmel programming tools.
2. Requires adapter or squid cable to connect a JTAGICE mkII (refer to AVR
Studio help).
3. It is only required to connect one V3P3/GND pin.
The AT90USB1287 can be programmed by connecting a programming tool, such as
a JTAGICE mkII, to the “JTAG USB” pin header (J200) on the Xplain board. Please
refer to AVR1907: Xplain Hardware User’s Guide for details.
4.2 The resistive touch pin-header (J101)
This connector connects the resistive touch interface to AVR XMEGA’s analog
PORTA that is available on the “XMEGA PORT A” pin header on the Xplain board
(J101). This allows the user to connect external signals to the ADC, DAC and Analog
Comparators on PORTA. Please see Table 4-2 below for pin-out description

stive touch pin-header (J101) connections.
