Using PDO/PDOCLK at same time with Port S SPI in S12ZVM

Hello,

 

Is it possible to use code profiling and the spi port S at the same time? I am unable to understand it from the Datasheet.

 

Thanks in advance.

 

Regards,

 

Hardy

Hi,

Hardly you can find a pin with two simultaneous functions. Two different peripheral interfaces cannot share a pin in the same time. But, for example PAD pin can have double function. It can serve as analog input to ADC and if enabled it can serve as digital input buffer. Still, this is not recommended, to have both digital and analog function.

So for the PDO/PDOCLK pin , if you use this DBG feature, it's better to route the SPI to Port T (if possible of course).

Also there is possibility to use S12ZVM256 derivative which has the option to configure SPI port to pins PS0-4 and so PS5/6 can be used with PDO/PDOCLK.
(expected launch of the S12ZVM256 derivative is planned for October/November this year).

Hope the information helps.


Have a great day,
iggi
