In order to receive a packet, the function checks if the netX Receive Mailbox Command flag and the Host
Receive Mailbox Acknowledge flag have different values. If so, the host application is allowed to access
the mailbox. When the host is done copying data from the mailbox, the host toggles the Host Receive
Mailbox Acknowledge flag to give control to the netX firmware.
