Help¶

This is the number of interrupt line used by the external timer. The special value of -1 allows using the internal timer in order to emulate an external timer. This is generally useful for running the project on a simulator where it is hard to emulate an external interrupt.

Direct dependencies¶

XTENSA_TIMER && !XTENSA_INTERNAL_TIMER

(Includes any dependencies from if’s and menus.)
