"The values of the IO Control registers are only writable if Init bit of CAN Control Register is Cleared." is written at "24.17.29 TIOC" and "24.17.30 RIOC" in TRM of TMS570LS2124.
Is the description correct?
In my condition, only when the Init bit of CAN Control Register is set (to 1), I can use CAN3 pins as GIO.
If I clear (to 0) the Init bit, TIOC and RIOC are initialized.
Could you teach me the correct flow to use CAN3 pins as GIO?
