Unread Message Interrupt Flag
Status flag indicating that a message has been received
but the existing message in that mailbox has not yet been
read due to the corresponding RXPR or RFPR set to 1.
The received message is either ignored (overrun) or
overwritten depending on the NMC (new message
control) bit.
Note: To clear this bit, clear the UMSR bit by writing 1 to
0: No message overrun or overwritten
1: Receive message overrun or overwritten

Mailbox Empty Interrupt Flag
This bit is set when at least one TXPR bit is cleared. It is
a status flag indicating that the mailbox is now ready to
accept a new transmit message. In effect, this bit is set
when any bit in TXACK or ABACK is set, therefore, this
bit is automatically cleared when all the TXACK and
ABACK bits are cleared.
