* `word hl`, `word bc`, `word de`: a 2-byte word byte passed via given 16-bit register
**Work in progress**:
Currently, only 3 parameter signatures are supported for non-macro assembly functions:
`()`, `(byte a)` and `(word hl)`. More parameters or parameters passed via other registers do not work yet.
Currently, only few parameter signatures are supported for non-macro assembly functions:

* `(byte a)`, `(byte b)`, `(byte c)`, `(byte d)`, `(byte e)`, `(byte h)`, `(byte l)` ("byte" may be any other 2-byte type)
* `(word hl)`, `(word bc)`, `(word de)` ("word" may be any other 2-byte type)

Macro assembly functions cannot have any parameter passed via registers.
