The routines are designed to be called as stand-alone subroutines in the user program or monitor mode.
The parameters that are passed to a routine are in the form of a contiguous data block, stored in RAM.
The index register (H:X) is loaded with the address of the first byte of the data block (acting as a pointer),
and the subroutine is called (JSR). Using the start address as a pointer, multiple data blocks can be used,
any area of RAM be used. A data block has the control and data bytes in a defined order, as shown in
Figure
During the software execution, it does not consume any dedicated RAM location, the run-time heap will
extend the system stack, all other RAM location will not be affected.
