TIM1 and TIM8 control register 1 (TIMx_CR1)
Address offset: 0x00
Reset value: 0x0000
参数介绍 Bits 9:8 CKD[1:0]: 时钟分频
该比特字段指示定时器时钟(CK_INT)频率与死区时间发生器和数字滤波器使用的死区时间和采样时钟(tDTS)(ETR、TIx):
00: tDTS=tCK_INT
01: tDTS=2*tCK_INT
10: tDTS=4*tCK_INT
11: Reserved, do not program this value
Bit 7 ARPE::自动重载使能
0: TIMx_ARR register is not buffered
1: TIMx_ARR register is buffered
