Hi,

I only found one note, that you should take into account:

Note of Table 7 (page 41):

1. When the I/O port is in input configuration and the associated alternate function is enabled as an output,

 

reading the DR register will read the alternate function output status.

 

2. When the I/O port is in output configuration and the associated alternate function is enabled as an input,

 

the alternate function reads the pin status given by the DR register content.

But there should be no problem at all, when you select the RDI pin as input (preferably with pullup) and the TDO pin as output (pushpull or with external pullup).

Regards,

WoRo

Thanks

How can I store the result of ADC conversion in the EEPROM?

Thanks

As I'm not familiar with the EvaBoard of Softec, I only can guess:

If you use the single step mode to check the program, the time from step to step may be the cause of setting the OIF??????

However, please post the part of your program, where you check the OIF and explain, how you are testing the sequence.
