• Packet received/transmitted. Also used
to detect overflow/underflow conditions
• CS
• PQT reached
• CCA
• SFD
Each of these events has a corresponding
interrupt flag in the RFIF register which is
asserted when the event occurs. If the
corresponding mask bit is set in the RFIM
register, the CPU interrupt flag S1CON.RFIF
will also be asserted in addition to the interrupt
flag in RFIF. If IEN2.RFIE=1 when
S1CON.RFIF is asserted, and interrupt
request will be generated.
Refer to 1.1 for details about the interrupts.
