1. Translate the logic to find the position of the first high in an 8 bit data item into program (Assembly or C language). The data must be read using interrupt driven SPI protocol. The data should be scanned from D7 to DO. Give the results for XX where XX is your Roll No. Register SPSR SPCR Bit-7 SPIF SPIE Bit-6 Bit-5 Bit-4 Bit-3 Bit-2 Bit-1 WCOL SPE DORD MSTR CPOL CPHA SPR1 Table.1 SPI Registers and their bit allocation Bit-o SPI2X SPRO The vector address for SPI ISR is at 0018 Hex address of ROM Location whereas its Vector Name in WinAVR is SPI_STC_vect. 2. Illustrate with a packet format for a master to write first three prime numbers to a slave address 1011111 using 12C protocol. 3. Develop an AVR code (Assembly or C language) to ask the student his/her attendance percentage through 12C protocol from a slave with address 1101110 with 50KHz frequency. The student should be allowed to sit in an exam if his/her attendance is greater than or equal to 75%, condoned if greater than 65% or equal, but less than 75% and not eligible if less than 65%.
