//! 2. Using the Mailbox mechanism which can be used when the Host can write
//!     the parameters to the mailbox Host-to-Device buffer region and then
//!     trigger an interrupt to the Device. The HIC module with the
//!     other application running on device side can then be used
//!    to signal to the host, using the Device-to-Host buffer region
//! in response.
//!  This API enables the access to the Device region and Mailbox.
//!  This should be used as the first API in sequence of configuring
