void ICACHE_FLASH_ATTR myt_init(void)
{
#define NMI_SOURCE_SEL_REG 0x3ff00000
WRITE_PERI_REG(NMI_SOURCE_SEL_REG, (READ_PERI_REG(NMI_SOURCE_SEL_REG)&~0x1F)|(0x1+0x7*2) );

NmiTimSetFunc(mytpwm_tim1_intr_handler);

RTC_REG_WRITE(FRC1_CTRL_ADDRESS, FRC1_CTRL_DIV_V | FRC1_ENABLE_TIMER | TM_EDGE_INT);

RTC_REG_WRITE(FRC1_LOAD_ADDRESS, FRC1_TOTAL_LOADV);

TM1_EDGE_INT_ENABLE();
ETS_FRC1_INTR_ENABLE();

}
