CAN Port Clocking

The CAN controller (SJA1000) can be clocked by 2 different frequencies.
Command Operation
CC? Query the CAN clocking selection.
CC=v Set the CAN clock selection.

Board Configuration

This product contains a group of registers that are used at "run-time" to perform a variety of functions. This
Command sets or shows the Base IO Address setting for these registers.
Command Operation
BP? Query the Board Base IO Address setting.
BP=v Set the Board Base IO Address setting.

J1708 Configuration

On this product the J1708 controller is implemented within the FPGA and is separate from the Uart Serial
Ports. These commands allow the J1708 Port to be configured with Address and IRQ assignments. The
assignments can also be queried.
Command Operation
J? Query the J1708 Base Address and IRQ settings
JP? Query the J1708 Base Address setting
JI? Query the J1708 IRQ setting
JS? Query the Enable / Disable state of the J1708 Port.
JP=v Set the J1708 Port Base Address.
JI=v Set the J1708 Port IRQ.
JS=v Set the Enable / Disable state of the J1708 Port.
Notes:
1. The value specified for the JP= command varies depending on whether the IO or MEMORY region is desired for the
J1708 Port. When IO region is desired, the value for the JP= command is a 3 digit IO address in Hex (000 to FE0 or
F80). When MEMORY region is desired, the value is a 6 digit Hex value (000000 to FFFFE0 or FFFF80).
When the J1708 Port is disabled...
2.

The decoding of the IO or Memory space is disabled.

The Port's interrupt signal is disconnected (disabled) from asserting the IRQ.

Notes
v = 16 or 24 (value indicates the frequency in MHz)
Notes
v= Base Address value can be from:
See the IOD command for setting the IO decoding
width, and the resulting IO address range.
Notes
v= Base Address value
See Note [1] below.
See the IOD command for setting the IO decoding
width, and the resulting IO address range.
v= IRQ selections:
3,4,5,6,7,9,10,11,12,14,15
v = 'E' to enable the Port
'D' to disable the Port
