Compiler/TMS320F28335: I/O Output logic interference

William Yan
Prodigy 210 points

Part Number: TMS320F28335

Tool/software: TI C/C++ Compiler

Hello:

I/O Output logic interference.

For example: debug mode  when i change PIN22&PIN23 output at the same time, one of the PIN22&PIN23 output error .

 PIN24/25 is the same.

by the way TMS320F2812  no similar problems have occurred

Although the actual application rarely changes the output of two I/Os at the same time,

I want to know what is the reason, whether it is my usage or the relationship of the chip itself.

THKS
