23.6.6 Receive Interrupts
Several Interrupts are linked to the message reception. The receive interrupts can be broken up
into two separate groups:
• Receive Error Interrupts
• Receive interrupts
23.6.6.1 Receive Interrupt
A message has been successfully received and loaded into one of the receive buffers. This inter-
rupt is activated immediately after receiving the End-Of-Frame (EOF) field. Reading the RXnIF
flag will indicate which receive buffer caused the interrupt. Figure 23-11 depicts when the receive
buffer interrupt flag RXnIF will be set.
23.6.6.2 Wake-up Interrupt
The Wake-up interrupt sequences are described in Section 23.13.1 “Operation in Sleep
Mode”.
