* Set compare time register (MTIMECMP) for generating interrupts. |
* |
* @note The interrupt is triggered when MTIME >= MTIMECMP. |
* @note The interrupt is acknwoledged by writing to the MTIMECMP.HI register. |
* @note The timer interrupt is enabled via neorv32_cpu_mti_enable(void) and disabled via neorv32_cpu_mti_disable(void). |
* @note Global interrupts have to be enabled via neorv32_cpu_eint(void). |
* @note Global interrupts and the timer interrupt source have to be enabled . |
* |
* @param[in] timecmp System time for interrupt (uint64_t) |
