Writing to one of the four message registers (MSGR0–MSGR7) causes a messaging interrupt as directed
by the other message registers listed above. Reading a message register clears the messaging interrupt.
Note that a messaging interrupt can also be cleared by writing a one to the corresponding status field of
the PIC message status register (MSR), shown in
9.3.5.1
The message registers (MSGR0–MSGR7), shown in
Table 9-30
9.3.5.2
The MER, shown in
be set to enable interrupt generation when the corresponding message register is written.
When bits in MER are set to mask message interrupts, an interrupt is not generated if the message register
is written while it is masked in MER and the MER bit is then cleared. To mask the interrupt without loss,
set MIVPRn[MSK]. (See
MER should be set to 0x0000_000F at reset and then left unchanged during normal operation.
