Help for STR712FZ2144Pin Port2 problem

Hi

We've encountered a problem in STR712FZ2 LQFP144Pin Port2 usage.

We cannot make proper use of the GPIO2 port (GPIO0 and GPIO1 are confirmed work OK) - Even the PC0, PC1 and PC2 registers are set as the same way as GPIO0 and GPIO1.

When any pin of GPIO2 was configured as OUT put pin, any INPUT pin of GPIO2 can not read in the input status. While if all the GPIO2 pins were configured as INPUT pin, the GPIO2 works well.

The mcu is STR710FZ2T6, LQFP144 package.

BTW. We have used STR710FZ2 LQFP64 IC for about 2 years and the 64pin IC work well. Is there any problems in 144Pin port2?

Did anybody have similar problem with this and give some help for me?

Regards,

bill

Hello,

Let me confirm there is no issue with GPIO2 port on 144pin package and no difference between 64pin and 144 pin package regarding the GPIO functionality. The only difference is 64pin includes only GPIO0 and GPIO1 whereas 144pin package has in addition GPIO2 port. do you still have any problem?
