J1850 Byte Level Protocol Decoder (JBLPD)
J1850 BYTE LEVEL PROTOCOL DECODER (Cont’d)
Bit 0 = IBD Invalid Bit Detect.
The IBD bit gets set whenever the receiver detects
that the filtered VPWI pin was not fixed in a state
long enough to reach the minimum valid symbol
time of Tv1 (or 35 µs). Any timing event less than
35 µs (and, of course, > 7 µs since the VPWI digit-
al filter will not allow pulses less than this through
its filter) is considered as noise and sets the IBD
accordingly. At this point the JBLPD peripheral will
cease transmitting and receiving any information
until a valid EOF symbol is received.
IBD errors are inhibited if the JBLPD peripheral is
in the “sleep or filter and NOT presently transmit-
ting” mode. An IBD error occurs once for a frame.
Afterwards, the receiver is disabled until an EOFM
symbol is received, and queued transmits for the
present frame are cancelled (but the TRA bit is not
set).
IBD is cleared when ERROR is read. Note that if
an invalid bit is detected during a bus idle condi-
tion, the IBD flag gets set and a new EOFmin must
be seen after the invalid bit before commencing to
receive again. IBD is also cleared while the CON-
TROL.JE bit is reset or while the CONTROL.JDIS
bit is set and on reset.
0: No invalid bit detected
1: Invalid bit detected
JBLPD INTERRUPT VECTOR REGISTER (IVR)

Bit 7:3 = V[7:3] Interrupt Vector Base Address.
User programmable interrupt vector bits.
Bit 2:1 = EV[2:1] Encoded Interrupt Source (Read
Only).
EV2 and EV1 are set by hardware according to the
interrupt source, given in

tion of the meaning of the interrupt sources)

JBLPD PRIORITY LEVEL REGISTER (PRLR)
R249- Read/Write
Register Page: 23
Reset Value: 0001 0000 (10h)
Bit 7:5 = PRL[2:0] Priority level bits
The priority with respect to the other peripherals
and the CPU is encoded with these three bits. The
value of “0” has the highest priority, the value “7”
has no priority. After the setting of this priority lev-
el, the priorities between the different Interrupt
sources and DMA of the JBLPD peripheral is hard-
ware defined (refer to the “Status register” bits de-
scription, the “Interrupts Management” and the
section about the explanation of the meaning of
the interrupt sources).
Depending
TIONS.DMASUSP bit, the DMA transfers can or
cannot be suspended by an ERROR or TLA event.
Refer to the description of DMASUSP bit.
