About far pointer in codewarrior 5.2

Excuse me: in the serial interrupt service program, a far pointer points to the receive data buffer, the buffer is in PAGED_RAM area, use the far pointer to write the received serial data to this buffer. Is this OK?

Hello,

 

Could you, please, share your project (to better understand your question)?

I'm not sure which MCU you use.

However, I would like to suggest looking at the SCI example, see attachment.

 

Thank you.

Best regards,

Diana
