Portmax_prigroup_bits
WebIn fact, when chip companies use this architecture to implement chip design, the priority group and the priority within the group are not used for all 8 bits, because a large number of priorities will Increase the complexity of the NVIC; therefore, in general, the specific chip, the 8 bit of PRI_0 will only use a part of the bit, of which ... WebIn fact, when using this architecture to achieve chip design, priority groups and group priority, not these 8 BITs, because a large number of priority Increase the complexity of NVIC;, in general, specific chips, PRI_0 8 bit will only use part of BIT, in which a few bit is used to represent a priority, with several bits to express the sub ...
