- Sound port (`06`) - the port to perform mono audio beeper operations;
- Syscall port (`07`) - the port to run system calls to the phone's underlying operating system.
Implementation note: direct writing to or reading from the control block memory area must have the same effect as calling the corresponding `DEO`/`DEI` instructions. E.g. if the application directly stores a byte into `#ffff`, the runtime must consider it writing to the `07` control port and process it as a system call.

E.g. if the application directly stores a byte into `#ffff`, the runtime may consider it writing to the `07` control port and process it as a system call. For now, this rule is not enforced and `DEO`/`DEI` instructions are the main source of truth when interacting with control block, but this can (and most likely will) change in the future specification versions.
