13 The ARM's Message-Handling-Unit (MHU) is a mailbox controller that has 3
22 interrupt signal using a 32-bit register, with all 32-bits logically ORed
24 check the status of each of the bits of this register independently. The use
25 of 32 bits per interrupt line enables software to provide more information
28 interrupt. Each of the 32-bits can be used as "doorbell" to alert the remote
