* Input Parameters:
- * page - The page index to be checked.
+ * index - ordinal number of the set of erasable units of memory
*
* Returned Value:
* Returns number of bytes NOT erased or negative value on error. If it
- * returns zero then complete page is erased.

* Name: up_progmem_write
*
* Description:
* Program data at given address
*
- * Note: this function is not limited to single page and nor it requires
- * the address be aligned inside the page boundaries.
+ * Note: This function may cross memory boundaries so long as the caller
+ * has ensured all units of memory that will be programmed have been
+ * erased. It also does not require that the write be aligned with the
+ * beginning of a unit of memory.
*
* Input Parameters:
* addr - Address with or without flash offset
- * (absolute or aligned to page0)
+ * (absolute or aligned to sector0)
Review comment:
@davids5 I believe I have addressed all of your comments except this
one. The up_progmem_getaddress() interface could be used to get the base
addresses of memory. Is this not sufficient? Or perhaps I don't understand your
concern fully.
