PAD configuration table for AM335x

DavidVescovi

I am use to seeing a pad configuration table (like in the 35XX TRM) that showed the physical address and possible mode selection for each and every pad. I used this quite a bit to get at the address and available modes for programming. I do not see this table in the AM335X TRM is there a reasion? The pin mux utility is nice but it does not show the register addresses.

Hi David,

Please check Table 2-7 in the AM335X Datasheet (http://www.ti.com/lit/gpn/am3359).

Table 2-7 is not the same thing. It is not what I am looking for as it does not have the register addresses.

I am looking for a table like table 7-4 in the http://www.ti.com/litv/pdf/spruf98x or 7-66 but for the AM335X.

I am looking for something like table 7-4 in the spuf98x (OMAP35x TRM) but for the AM335x.

Hi David,

I understand. Well, it's more obscure here. What you need is section 9.3.50 "conf_<module>_<pin> Register (offset = 800h–A34h)", which describes the register contents, along with Table 9-10, which describes the register offsets. All of this used in conjunction with the Datasheet Table 2-7 will give you the required information.

I agree with you that the OMAP35X table is much easier to use.
