Zero Page Mode¶
Syntax¶
instruction zero_page_address
Description¶
In the zero page addressing mode, the effective address is a single byte zero page address specified in the instruction. The instruction operates on the memory location pointed to by this address.
Example¶
Here’s an example using the LDA instruction in zero page addressing mode:
LDA $10
The instruction will load the value at memory location $10 into the accumulator.
Use Cases¶
Zero page addressing mode can only access memory locations in the range of 0 to 255. Due to the limited number of registers, the zero page is often used to store frequently accessed variables. It is also used frequently to store pointers, since the indirect modes can only operate on the zero page area.
