TM4C1230D5PM: GPIOIntEnable() cannot be used

Part Number: TM4C1230D5PM

Hi,

TM4C1230D5PM is classified as Blizzard by Tivaware, and GPIOIntEnable() is not allowed.

However, this function is only about setting up GPIO_O_IM (offset 0x410) register, which is a valid one as per the datasheet. 

Is this an error of Tivaware?

My Tivaware version is 2.1.4.178

    Sorry, my post was not accurate. GPIOIntEnable() was allowed to used. The issue was I could not replace it by the ROM_function. i.e., I cannot change the function to ROM_GPIOIntEnable() to switch it to the in ROM code.

    Hi Tianlei,

      Some ROM_xxx APIs may be deprecated due to bugs. You can look at the rom.h file. As you can see that ROM_GPIOIntEnable is only available forTM4C129 MCU. If you look further down, for example, the ROM_HibernateIntClear is available for both TM4C123 as well as TM4C129. This is why we don't recommend calling ROM_xxx directly but rather calls MAP_xxx instead. If a ROM_xxx is available, then the MAP_xxx will result to calling ROM_xxx. If the ROM function is not available, then the MAP_xxx will result to calling xxx function that is built into the driverlib.lib.
