Other Parts Discussed in Thread: SYSCONFIG
When I was checking the datasheet of the F280023, there was a point that caught my attention, so let me confirm it just in case.
Q1:In the JTAG circuit, it is TRST open, but on the device side, it is Input pin, so there is no problem. Is this concept correct?
Q2:The RX and TX of SCI-A and LIN-A of GPIO28/29 are different from each other. Is the datasheet correct?
Considering the boot pin settings, the combination of SCIRXDA:GPIO28 and SCITXDA:GPIO29 is correct. Also, the SysConfig settings are the same as in the datasheet, but I was curious because the relationship between SCI and LIN is different for this pin only.
