Question one 1. Analyse the following C-code and give the content of the variable result in hex notation: unsigned int Value = 0x12; unsigned char Number = 0x34; unsigned int Result = 0; Value = Value< 8; Value = Value | Number; Result = ((Result + Value) & 0XA4D0); 2. Calculate the execution time of the following code (Fosc = 12 MHz): MOV A,#0x07 MOV B,#0x50 MUL AB SWAP A 3. Analyse the following assembly code and give the content of register B in hex format: MOV B,#0x37 MOV 0x30,#0x03 MOV A,B Loop: RL A DJNZ 0x30,Loop MOV B,A 4. 127 bytes asynchronous data is serially transmitted at a rate of 19200 Baud. How much transmission time is needed by the 8051 microcontroller to complete the task? No parity is used. 5. Analyse the following C-code and give the content of the variable result: unsigned char Val_1 = 56; float Val_2 = 3.281; unsigned int Result; Result = Val 1 * Val 2;
