The mailbox module provides a means of communication through message queues among the users. The individual mailbox modules, or FIFOs, can associate (or de-associate) with any of the processors using the MAILBOX_IRQ_ENABLE_SET_j (or MAILBOX_IRQ_ENABLE_CLR_j) register.
Each user has a dedicated interrupt signal from the corresponding mailbox module instance and dedicated interrupt enabling and status registers.
Each MAILBOX_IRQ_STATUS_RAW_j/MAILBOX_IRQ_STATUS_CLR_j interrupt status register corresponds to a particular user.
