2.5 In-System Programming
The AT90CAN 128 can be p rogrammed usin g specific SPI links. This sub section will
explain how to connect the programmer.
The FLASH, EEPROM memory (and all Fuse and Lock Bit Option IS P-programmable)
can be programmed individually or with the sequential automatic programming option .
Note: When programming, the NISP jumper has to be removed.
2.5.1 Using the ATAVRAUTO900 Adaptator
The AVR ISP pr ogrammer is a compact and easy-to-use In-Syste m Programming tool
for developing applications with AT90CAN128. Due to the small size, it i s also an excel-
len t too l for f iel d u pg rad es of ex is tin g a pp lic ati ons . It is po we red by t he
ATAVRAUTO10 0 and an a dditional powe r supply is thus not r equired. The AVR ISP
programming interface is i ntegrated in AVR Studio®. An additional adaptator has to be
used to program the board using ISP or JTAG mode. The 10 pins connector is used for
the JTAGICE mkII device and the 6 pi ns connector is used for the AVRISP device. To
plug the ATAVRAUTO900 connector to the board, the arrow (on the adaptor) has to be
in front of the point (on the board).
