What are the different fields present in ALP (PAL – Practice Assembly language)? |
|
Answer» PAL contains three internal registers: Register A: Performs all operations in the CPU. Register B: Stores numbers temporarily. Register PC: Holds the address of the next instruction to be executed in code memory. Register A and R can hold 8 bits of binary data and register PC can hold a 16-bit address number. PAL is called an 8-bit computer because the working registers A and R can hold a 1-byte number. PAL register PC limits the number of code byte addresses to 64k because it can hold code address from address 0000H to address FFFFH. |
