I don’t understand what you mean by “Table 9.15”
Table 9 is a map of the tertiary interrupt controller.
Table 15 is a map of interrupt controller registers.
The first table in chapter 9 is table 22.
I don’t want the bits of the interrupt controller; I want the bits of the pull-up/down registers.
For example: Both Table 25 and Table 29 define “TRISTATE_CONTROL”
Table 23 also says that each pin has a Tristate_control.
But, there’s no mapping that shows me what bit value that constant has – where do I find the TRISTATE_CONTROL for a particular GPIO pin?
… Oh, I see. What’s called TRISTATE_CONTROL in those three tables, is actually called just TRISTATE in the un-numbered tables in section 9.
So, if I start from the top, and see “TRISTATE_CONTROL,” I have to just guess that, actually, these pins will be called “TRISTATE” in the register map.
I guess I picked a bad example to search for, because PUPD seems to map better between the overview tables and the register bit mask documentation.
Separately, by “Table 9.15” perhaps you meant “the various un-numbered tables found in section 9.15.”
Thanks for the pointer!
