J1850 Byte Level Protocol Decoder (JBLPD)
J1850 BYTE LEVEL PROTOCOL DECODER (Cont’d)
Bit 5 = RDRF_M Receive Data Register Full Inter-
rupt Mask bit.
This bit enables the “receive data register full” in-
terrupt source to generate an interrupt request.
This bit is reset if the CONTROL.JDIS bit is set at
least for 6 clock cycles (3 NOPs).
0: RDRF interrupt source masked
1: RDRF interrupt source un-masked
Bit 4 = TLA_M Transmitter Lost Arbitration Inter-
rupt Mask bit.
This bit enables the “transmitter lost arbitration” in-
terrupt source to generate an interrupt request.
This bit is reset if the CONTROL.JDIS bit is set at
least for 6 clock cycles (3 NOPs).
0: TLA interrupt source masked
1: TLA interrupt source un-masked
Bit 3 = RXD_M Receiver DMA Mask bit.
If this bit is “0” no receiver DMA request will be
generated, and the RDRF bit, in the Status Regis-
ter (STATUS), can request an interrupt. If RXD_M
bit is set to “1” then the RDRF bit can request a
DMA transfer. RXD_M is reset by hardware when
the transaction counter value decrements to zero,
that is when a Receiver End Of Block condition oc-
curs (REOBP flag set).
This bit is reset if the CONTROL.JDIS bit is set at
least for 6 clock cycles (3 NOPs).
0: Receiver DMA disabled
1: Receiver DMA enabled
Bit 2 = EODM_M End of Data Minimum Interrupt
Mask bit.
This bit enables the “end of data minimum” inter-
rupt source to generate an interrupt request.
This bit is reset if the CONTROL.JDIS bit is set at
least for 6 clock cycles (3 NOPs).
0: EODM interrupt source mask
1: EODM interrupt source un-masked
Bit 1 = EOFM_M End of Frame Minimum Interrupt
Mask bit.
This bit enables the “end of frame minimum” inter-
rupt source to generate an interrupt request.
This bit is reset if the CONTROL.JDIS bit is set at
least for 6 clock cycles (3 NOPs).
0: EOFM interrupt source masked
1: EOFM interrupt source un-masked

Bit 0 = TXD_M Transmitter DMA Mask bit.
If this bit is “0” no transmitter DMA request will be
generated, and the TRDY bit, in the Status Regis-
ter (STATUS), can request an interrupt. If TXD_M
bit is set to “1” then the TRDY bit can request a
DMA transfer. TXD_M is reset by hardware when
the transaction counter value decrements to zero,
that is when a Transmitter End Of Block condition
occurs (TEOBP flag set).
This bit is reset if the CONTROL.JDIS bit is set at
least for 6 clock cycles (3 NOPs).
0: Transmitter DMA disabled
1: Transmitter DMA enabled

Bit 7 = INPOL VPWI Input Polarity Selector.
This bit allows the selection of the polarity of the
RX signal coming from the transceivers. Depend-
ing on the specific transceiver, the RX signal is in-
verted or not inverted respect the VPWO and the
J1850 bus line.
0: VPWI input is inverted by the transceiver with
1: VPWI input is not inverted by the transceiver
Bit 6 = NBSYMS NB Symbol Form Selector.
This bit allows the selection of the form of the Nor-
malization Bits (NB0/NB1).
0: NB0 active long symbol (Tv2), NB1 active short
1: NB0 active short symbol (Tv1), NB1 active long
