MPC5748G 的 FlexCAN模块,想使用FD模式,但发现CTRL2_ISOCANFDEN位不能置1.确认已经在Freeze模式。
芯片版本SPC5748GSMKU6_1N81M_QAD1731AD
I want to use the FlexCAN operates using the ISO CAN FD protocol (ISO. 11898-1), I use the chip MPC5748G, the chip will need to register CTRL2 reference manual ISOCANFDEN position is 1, but in MPC5748G.h in the absence of such a definition, I added, in the software in the operation also has been unable to successfully register, CTRL2 ISOCANFDEN is always 0. has been confirmed in Freeze mode.
I Sample MASK is SPC5748GSMKU6_1N81M_QAD1731AD
Hello,
unfortunately, mask 1N81M has non-ISO CAN-FD module, so it is not possible to write 1 into SOCANFDEN bit. You need microcontroller with the newest mask 0N78S.

thank you!
Does the following chip support CANFD-ISO?
mask
SPC5746CSM
MH6 1N06M
CTAD1628J
Hello,
unfortunately, this microcontroller does not support ISO CAN-FD. I recommend you use the newest mask which is 1N84S for MPC5746C.
