Answer the following statements with True or False. You don't need to give details, just write True or False. 1.1. To convert from ASCII to BCD the value 30H is subtracted from the ASCII value and answer of the subtract operation will be the corresponding BCD digit. (2) 1.2. Every one of the interrupts can be enabled individually by setting or clearing a bit in the Special Function Registers PIE1 (8Ch) and PIE2 (8Dh). (2) 1.3. The PIC16F877A device provides fifteen different interrupt sources. (2) 1.4. After processing, the TOIE flag should not be cleared by the software. (2) (2) 1.5. The switch on a keyboard, is in most cases, a normally open push to make switch. 1.6. Input port pins do not need to be able to distinguish clearly between a "1" and a "0", especially if the signal makes a transition from one level to the other. (2) 1.7. The idea behind indirect address is to use one of the registers as a "pointer" to indicate which address will be operated upon. (2) 1.8. Software timing delays are routines that are quite widely used in programming as it is used in a variety of I/O interfacing tasks and general programming. (2) 1.9. If a branch operation has to take place, the program counter has to be reloaded with the address of the last instruction in the branch. (2) 1.10. With a pipeline the CPU can fetch an instruction from the memory and while that instruction is being decoded and executed, the next instruction is fetched and held in the pipeline, ready to be decoded next.
