Part Number: AM6412
Tool/software:
Hi T.I community expert,
1) There is something which is not clear about MMC0_CLK recommandations:
When looking at the datasheet (2024) table 5-80 one can read the following :
==> MMC0_CLK can be left open when not used
But on page 94 there is a note specifying some case where external pull is required:
The problem is that MMC0_CLK is also described in table 5-1 as being RX : ON after boot without any internal pull inside. This would therefore require an external pull when not used.
Is there something I am missing ?
2) I also have the same kind of question regarding I2C0_SCL which is described as RX : ON after BOOT. However I could not find recommandations about external pull when not used.
Can you confirm ? or not ?
With best regards
Bruno
