웹2015년 10월 30일 · - BASEPRI: a register of up to 8 bits (depending on the bit width impl'd for priority level). It defines the masking priority level. When set, it disables all interrupts of the same or lower level (larger priority values). Higher priority interrupts can still be allowed. If this is set to 0, the masking function is disabled (this is the default). 웹2024년 8월 19일 · 在 FreeRTOS 中，对中断的开和关是通过操作 BASEPRI 寄存器来实现的，即大于等于 BASEPRI 的值的中断会被屏蔽，小于 BASEPRI 的值的中断则不会被屏蔽，不受FreeRTOS 管理。 3.3 关中断.
