Byte sampling in BOM Mode
a)
b)
Two different BOM reception modes may be programmed (CCR1.BRM).
10 byte packets: After storing 10 bytes in RFIFO the receive status byte marking a BOM
frame (RSIS.HFR) is added as the eleventh byte and an interrupt (ISR0.RME) is
generated. The sampling of data bytes continues and interrupts are generated every 10
bytes until an HDLC flag is detected.
Continuous reception: Interrupts are generated every 32 (16, 4, 2) bytes. After
detecting an HDLC flag, byte sampling is stopped, the receive status byte is stored in
RFIFO and an RME interrupt is generated.
The user may switch between these modes at any time. Byte sampling may be stopped
by deactivating the BOM receiver (MODE.BRAC). In this case the receive status byte is
added, an interrupt is generated and HDLC-mode is entered. Whether the FALC54
operates in HDLC or BOM mode may be checked by reading the Signaling Status
Register (SIS.BOM).
