It's impossible :o) You can disable and enable any interrupt source by setting or clearing corresponding bit in proper control register. Show me your code - we will see what can be done wrong.

You can set bit I on SREG by 1 to enable global interrupt or by 0 to disable it.

in c programming you can write

#asm ("sei") //to enable global interupt

#asm ("cli") //to disable global interupt

Cache is a high speed memory which is basically used for the following reason:

As the speed of the main memory is not as much as the speed of the CPU.so just to compensate the speed mistmatch between the CPU and main memory the cache is used in between the two.so whenever the CPU asks for any data its being checked with the cache memory and if present then "cache hit" occurs or else "cache miss" occurs wher the CPU takes the data form the main memory and that data's cpoy is being send to the cache for any further operation where the CPU can request for the same data.

Complex programmable logic device (CPLD) are programmable digital logic devices which are simpler and lesser capacity than FPGA (Field Programmable Gate Arrays) devices. CPLDs have a non-volatile memory (i.e. turning off the power does not require reprogramming of CPLD)

Microcontrollers (uP or MCU) are small and cost effective but self contained computer chips (compared to general purpose processor chips used in personal computers) used for embedded applications in industrial, consumer electronics products and automobiles. Microcontrollers may or may not have inbuilt memory.

CPLDs are used for implementing logic but they do not have a embedded processor like in microcontrollers.

All micro-controllers are going to be difficult to use, because you build your circuits around them, not vice versa. From a programmer perspective, the BASIC Stamp uses PBasic which is very easy to use and understand. The PIC16F84 Micro series uses assembly, but only has 30 commands and is much more powerful IMHO.

just a note: Clarify your question

Bit-addressable registers are registers that its bits can be modified individually. that means if you have register named "ACC" that is bit addressable , you can change its bits (D0 -D7) individually by special instructions SETB and CLR.

ex: SETB ACC.3 ; will set bit number 4 (remember bit 0) in the register

in 8051 there are many bit-addressable registers such as A (ACC), B, SCON, PCON, TCON, p0,p1,p2,p3 .

Two typical components of a CPU are:

The arithmetic logic unit (ALU), which performs arithmetic and logical operations.

The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.

Additional time required because of a miss it is generally the 30~40 cycles for Main Memory.

Because it is 8- 8-bit controller (8000 series)

5- It has 5 interrupts

1- It has only one serial communication port

Incorrect. Fetching and decoding of any instruction takes a minimum of four clock cycles in the 8085.

T1 = ALE and address emission

T2 = Read initiation

T3 = Read completion

T4 = Opcode decode

T1, T2, and T3 are repeated for each additional byte of the instruction. In all cases, Twait, if indicated by not READY, is inserted between T2 and T3.

Thermal design power (TDP), sometimes called thermal design point, represents the maximum amount of power the cooling system in a computer is required to dissipate.
