Example of a BCALL Wiki
If your BCALL is something simple, you may omit some (or all) of these sections and just give a Synopsis. Please provide as many sections as you can.
Synopsis
Official Name: SomeCall
"BCALL Address: $4444
This ROM Call does absolutely nothing since it doesn't exist. :)
Inputs
- a: Page to look copy from
- de: Address to copy to
- hl: Address to copy from
- (de): A byte is copied from here
- keyExtend: An example of a known RAM block.
- bit exampleBit, (iy+demoBye): Set to do something, reset to do something else
- Parity: Set for something
Outputs
- (hl): A byte is copied to here
- Zero: Set if successful
Registers Destroyed
- af
Example
ld a,$08 ld de,$567A ld hl,keyExtend b_call SomeCall
