Original question:
Dear Sir/Ms.
I would like to ask if the TPS92662 can be connected as shown below, through the DEVID segment in the communication protocol.
DEV_ID[4:0]. Set as follows:
RH:
TPS92662 : DEV_ID[4:0]0x01
MCU: DEV_ID[4:0]0x03
LH:
TPS92662 : DEV_ID[4:0]r0x02
MCU: DEV_ID[4:0]0x04
Best Regards,
Kami Huang
Hello Kami,
It can be made to work but it may not be easy.
From a colleague:
"This system as shown in the figure can be made to work. Here are the requirements:
(1) The same clock frequency must be used for both modules.
(2) Since this is a CAN system, the SEPTR bit (Reg. 80h bit 7) must be zero.
(3) The two MCU’s must respond to the same protocol as the TPS92662 devices. This is because of the BUS Parking feature designed into the TPS92662. Here is the snippet from the data sheet:
TI has not tested this but from our knowledge of how the TPS92662 is designed, we expect this to work as long as the above requirements are met.
Best Regards,
