* In System programming and Multi-processor communication between master and salve
microcontroller
MOSI, MISO, SCK and SS pins of ATMEGA2560 (master microcontroller) are connected to the
ISP (In System programming) port as well as the SPI bus of ATMEGA8 (slave microcontroller).
Hence to do ISP you need to disconnect jumper J4 on the microcontroller adaptor board. To
access data from the slave microcontroller ATMEGA8 over SPI bus Jumper J4 on the
microcontroller socket needs to be connected.
