ID
NAME
SIGNAL

DESCRIPTION
0x11E
ERR
COMMERR
Bool, [0] (4)
FIFOWROVR
Bool, [0] (5)
FIFOTAGERR
Bool, [0] (6)
OTHER
Bool, [0] (7)
TIMEOUT
Bool, [0] (3)
FIFOALLERR
Bool, [0] (2)
PECERR
UInt, [0] (1:0)
Error message. Combination (ORing) of error codes (bits [7:2]) and PEC error counter (bits [1:0]). The PEC counter counts the PEC errors when receiving
data from the LTC2949 and will stop counting at 3.
Note:
“T, [Byte], Bits” indicates the type and number of bits. For example, “Int, [0], 8” refers to an 8-bit integer value stored in CAN message data byte 0.

CH1FAST
Bool, [0] (0)
CH1 fast enable flag
CH2FAST
Bool, [0] (1)
CH2 fast enable flag
AUXFAST
Bool, [0] (2)
AUX fast enable flag
FCONT
Bool, [0] (3)
fast continuous enable flag (fast measurements will be stored within FIFO, otherwise
fast single shot measurements will be performed upon request, see FASTRQ)
SLOT1NTC
Bool, [0] (4)
SLOT1 temperature measurement via NTC enable flag
SLOT2NTC
Bool, [0] (5)
SLOT2 temperature measurement via NTC enable flag
If enabled an NTC must be connected to the voltage inputs selected via SLOTxP/N which then will be used for temperature measurements.

Power1 as voltage enable flag
P2ASV
Bool, [0] (7)
Power2 as voltage enable flag
SLOT1P
UInt, [1] (3:0)
