Answer by placing for True or for Fabe in the brackets the question if you are not sure of the answer te the correct answer counts as 2 and the wrong answer counts as therefore it is better to leave 3. 4 1. (X). Non maskable interrupt can be ignored by setting certain bits in the templates clearing 2. Once the microcontroller is servicing an interrupt, then another device can not interrupt the 8051, and thus has to wait. The Interrupt vector table is fixed and cannot be changed, (le cannot change the address.) 4. in On reset, all interrupts in the 8051 are disabled. 5. (X) On execution of the ISR, the Tex flags are reset by the Hardware, that is the programmer has to clear it. (%) The maximum delay in timer-O in mode-2 is obtained when the timer is loaded with IF 7. (%) Maximum square wave frequency obtained is when the delay is the highest *8. The programmer can set the system to any Boud Rate if he wishes to transmites date serially or in Parallel. 6. 034 134 9. (%) When the 8051 receives and an interrupt and vectors to address 23H, then it can know that it has received an External Interrupt. * 10. (*) We cannot generate frequencies that are higher that the oscillator frequency
