10.3.5.2
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
(MIVPR0–MIVPR3).”) MER should be set to 0x0000_000F at reset and be left unchanged during normal
operation.

10.3.5.3
The PIC message status register (MSR) shown in
register. The status bit is set when the corresponding messaging interrupt is active. Writing a one to a status
bit clears the corresponding message interrupt and the status bit.
