Receive-Ready Registers
These register bits can be reset by writing ’0’ to the respective bit, writing ’1’ has no effect. Bit RRn
is set when a message has arrived and been written into the memory location of message n. Setting
this bit by hardware can generate a receive interrupt, which can be blocked by bit RIMn in the
receive-interrupt-mask register.
Bits RRn must be reset by software.
Receive-Interrupt-Mask Registers
Setting bit RIMn enables a receive interrupt to be generated if the receive-ready bit RRn has been
set, i.e. a message has arrived and was written into the memory location of message n.
Note:
Bit ERI in the interrupt-mask register IM blocks all receive interrupts, even if bits RIMn are
set.
