Rajveer Chatterjee answered |
The concatenated register of MC68HC11 is the D register. The MC68HC11 is a microcontroller unit (MCU) developed by Motorola. It is widely used in embedded systems and has a wide range of applications.
- The MC68HC11 has a total of 16-bit data registers, which are divided into four 8-bit registers called D0, D1, D2, and D3.
- These four registers can be concatenated to form a 16-bit register called the D register.
- The D register allows for easy manipulation of 16-bit data. It is particularly useful for arithmetic and logical operations that involve 16-bit values.
- The D register can be accessed as a whole or can be split into its constituent 8-bit parts (D0-D3).
- The D register is commonly used for storing temporary variables, intermediate results, and data that requires 16-bit precision.
- The D register is also used for transferring data between memory and peripheral devices.
- In addition to the D register, the MC68HC11 also has other registers such as the X register, the Y register, the program counter (PC), and the data index register (D).
In summary, the concatenated register of MC68HC11 is the D register. It is a 16-bit register formed by concatenating the four 8-bit data registers (D0-D3). The D register is commonly used for arithmetic and logical operations involving 16-bit data and for transferring data between memory and peripheral devices.
