谁有8962时钟网络图 CAN模块输入时钟是什么
[复制链接]
TI例程里CAN的波特率配置没看明白,CAN模块的时钟是谁给的?
TI CANBitTimingSet()函数的说明里有这么一段:
The equation to determine the actual bit rate is as follows:
CAN Clock / ((uSyncPropPhase1Seg + uPhase2Seg + 1) *(uQuantumPrescaler))
This means that with uSyncPropPhase1Seg = 4, uPhase2Seg = 1, uQuantumPrescaler = 2
and an 8 MHz CAN clock, that the bit rate will be (8 MHz) / ((5 + 2 + 1) * 2) or 500 Kbit/sec.
uSyncPropPhase1Seg = 4, uPhase2Seg = 1,这两个参数为什么在计算的时候变成了 5和2
TI例程里面uSyncPropPhase1Seg = 5, uPhase2Seg = 2,那么在计算时候是不是就变成 6和3了呢?
请高人指点
