MPC5645S I/O PORT base address registers location

[peteradamcik]

Hi guys, I can't seem to find any info on the MPC5645S I/O Ports. I've checked in the reference manual 10x now and there's no info on the I/O Ports. I need info on the I/O registers like PORT base addresses, pulp, pulldown base address , PORT CTRL addresses. You get the picture, lol.

Most micro controller reference manuals have the I/O registers in one whole section called I/O Registers (lol) but I just can't find any I/O register section in the reference manual.

Is there another manual with the info that I haven't downloaded yet?

Please help me on this one.

Thanks guys

Peter.

All good, I found the BASE address. Base (0xC3F9_0000)

You may find it in section 3.3.9 

I/O setting then you are managing over SIU module (Chapter 43 System Integration Unit Lite (SIUL))

specifically over PCR registers:

Hi David, thank you for the info. Ahhh I see you call them PCR pins and not PRA0,PRA1 etc... for PORTA 0, PORTA 1 pins. So what is the BASE register. It says BASE address, what is the BASE address ?
