2.1.1 Jumper Description

Table 2-1 shows a description of the jumper selections on the EVM with a short description of the function of each pin.

Table 2-1 Jumper Definitions
Connection Type Transceiver Pin Description
JMP1 2-pin jumper nSTB Mode control input, Standby input, integrated pull down
JMP2 16-pin jumper nSTB
TXD CAN transmit data input (LOW for dominant and HIGH for recessive bus states), integrated pull up
RXD CAN receive data output (LOW for dominant and HIGH for recessive bus states), tri-state
EN Mode control input, Enable Input, integrated pull down
INH Inhibit output, controls system voltage regulators and supplies
nFAULT Fault output, inverted logic
WAKE Wake input terminal, high voltage input
INH_MASK INH_MASK input
JMP3 2-pin jumper CANH, CANL Connect 120-Ω CAN termination to the bus. Used separately for a single termination if EVM is at end of the CAN bus and termination is not in the cable. Used in combination with JMP5 to get to second CAN termination to represent the combined 60-Ω load for CAN transceiver parametric measurement.
JMP4 4-pin jumper CANH, CANL CAN bus connection (CANH, CANL) and GND
JMP5 2-pin jumper CANH, CANL Connect 120-Ω CAN termination to the bus. Used in combination with JMP3 to get to second CAN termination to represent the combined 60-Ω load for CAN transceiver parametric measurement.
TP1 Test point (loop) TXD CAN transmit data input
TP2, TP4 CANH High-level CAN bus I/O line
TP3 RXD CAN receive data output
TP5 EN Mode control input, Enable Input
TP6, TP7 CANL Low-level CAN bus I/O line
TP8 INH Inhibit output, controls system voltage regulators and supplies
TP9 nFAULT Fault output, inverted logic
TP10 WAKE Wake input terminal, high-voltage input
TP11 VCC 5-V supply voltage
TP12 VIO I/O supply voltage
TP13 VSUP Reverse blocked battery supply input
TP14, TP15, TP16 GND Ground connection
