RM0008手册中关于CHx和CHxN通道的输出电平与OSSI、OSSR、MOE、CCxE、CCxNE等位的关系表“Table 83. Output control bits for complementary OCx and OCxN channels with break feature”完全就是错误的! 下面是实测出来的结果: STM32F103VE TIM1 OSSI isn't cared OSSR isn't cared when MOE=0 0000000XX: 0 0 0000001XX: OC1REF ~OC1REF 0000010XX: OC1REF ~OC1REF 0000011XX: 0 0 0000100XX: OC1REF OC1REF 0000101XX: 0 1 0000110XX: 0 1 0000111XX: OC1REF OC1REF 0001000XX: ~OC1REF ~OC1REF 0001001XX: 1 0 0001010XX: 1 0 0001011XX: ~OC1REF ~OC1REF 0001100XX: 1 1 0001101XX: ~OC1REF OC1REF 0001110XX: ~OC1REF OC1REF 0001111XX: 1 1 0010000XX: 0 0 0010001XX: 0 1 0010010XX: 1 0 0010011XX: 0 0 0010100XX: 0 0 0010101XX: 0 1 0010110XX: 0 1 0010111XX: 1 1 0011000XX: 0 0 0011001XX: 1 0 0011010XX: 1 0 0011011XX: 1 1 0011100XX: 1 1 0011101XX: 0 1 0011110XX: 1 0 0011111XX: 1 1 0100000XX: 0 0 0100001XX: 0 1 0100010XX: 1 0 0100011XX: 0 0 0100100XX: 0 0 0100101XX: 0 1 0100110XX: 0 1 0100111XX: 1 1 0101000XX: 0 0 0101001XX: 1 0 0101010XX: 1 0 0101011XX: 1 1 0101100XX: 1 1 0101101XX: 0 1 0101110XX: 1 0 0101111XX: 1 1 0110000XX: 0 0 0110001XX: 0 1 0110010XX: 1 0 0110011XX: 0 0 0110100XX: 0 0 0110101XX: 0 1 0110110XX: 0 1 0110111XX: 1 1 0111000XX: 0 0 0111001XX: 1 0 0111010XX: 1 0 0111011XX: 1 1 0111100XX: 1 1 0111101XX: 0 1 0111110XX: 1 0 0111111XX: 1 1 10000000X: 0 0 10000001X: 0 0 10000010X: 0 0 10000011X: 0 0 10000100X: 0 0 10000101X: 0 0 10000110X: 0 0 10000111X: 0 0 10001000X: 0 0 10001001X: 0 1 10001010X: 0 0 10001011X: 0 1 10001100X: 0 0 10001101X: 0 1 10001110X: 0 0 10001111X: 0 1 10010000X: 0 0 10010001X: 1 0 10010010X: 0 0 10010011X: 1 0 10010100X: 0 0 10010101X: 1 0 10010110X: 0 0 10010111X: 1 0 10011000X: 0 0 10011001X: 1 1 10011010X: 0 0 10011011X: 1 1 10011100X: 0 0 10011101X: 1 1 10011110X: 0 0 10011111X: 1 1 10100000X: 0 OC1REF 10100001X: 0 OC1REF 10100010X: 0 OC1REF 10100011X: 0 OC1REF 10100100X: 0 OC1REF 10100101X: 0 OC1REF 10100110X: 0 OC1REF 10100111X: 0 OC1REF 10101000X: 0 ~OC1REF 10101001X: 0 ~OC1REF 10101010X: 0 ~OC1REF 10101011X: 0 ~OC1REF 10101100X: 0 ~OC1REF 10101101X: 0 ~OC1REF 10101110X: 0 ~OC1REF 10101111X: 0 ~OC1REF 10110000X: 0 OC1REF 10110001X: 1 OC1REF 10110010X: 0 OC1REF 10110011X: 1 OC1REF 10110100X: 0 OC1REF 10110101X: 1 OC1REF 10110110X: 0 OC1REF 10110111X: 1 OC1REF 10111000X: 0 ~OC1REF 10111001X: 1 ~OC1REF 10111010X: 0 ~OC1REF 10111011X: 1 ~OC1REF 10111100X: 0 ~OC1REF 10111101X: 1 ~OC1REF 10111110X: 0 ~OC1REF 10111111X: 1 ~OC1REF 11000000X: OC1REF 0 11000001X: OC1REF 0 11000010X: OC1REF 0 11000011X: OC1REF 0 11000100X: OC1REF 0 11000101X: OC1REF 0 11000110X: OC1REF 0 11000111X: OC1REF 0 11001000X: OC1REF 0 11001001X: OC1REF 1 11001010X: OC1REF 0 11001011X: OC1REF 1 11001100X: OC1REF 0 11001101X: OC1REF 1 11001110X: OC1REF 0 11001111X: OC1REF 1 11010000X: ~OC1REF 0 11010001X: ~OC1REF 0 11010010X: ~OC1REF 0 11010011X: ~OC1REF 0 11010100X: ~OC1REF 0 11010101X: ~OC1REF 0 11010110X: ~OC1REF 0 11010111X: ~OC1REF 0 11011000X: ~OC1REF 0 11011001X: ~OC1REF 1 11011010X: ~OC1REF 0 11011011X: ~OC1REF 1 11011100X: ~OC1REF 0 11011101X: ~OC1REF 1 11011110X: ~OC1REF 0 11011111X: ~OC1REF 1 11100000X: OC1REF ~OC1REF 11100001X: OC1REF ~OC1REF 11100010X: OC1REF ~OC1REF 11100011X: OC1REF ~OC1REF 11100100X: OC1REF ~OC1REF 11100101X: OC1REF ~OC1REF 11100110X: OC1REF ~OC1REF 11100111X: OC1REF ~OC1REF 11101000X: OC1REF OC1REF 11101001X: OC1REF OC1REF 11101010X: OC1REF OC1REF 11101011X: OC1REF OC1REF 11101100X: OC1REF OC1REF 11101101X: OC1REF OC1REF 11101110X: OC1REF OC1REF 11101111X: OC1REF OC1REF 11110000X: ~OC1REF ~OC1REF 11110001X: ~OC1REF ~OC1REF 11110010X: ~OC1REF ~OC1REF 11110011X: ~OC1REF ~OC1REF 11110100X: ~OC1REF ~OC1REF 11110101X: ~OC1REF ~OC1REF 11110110X: ~OC1REF ~OC1REF 11110111X: ~OC1REF ~OC1REF 11111000X: ~OC1REF OC1REF 11111001X: ~OC1REF OC1REF 11111010X: ~OC1REF OC1REF 11111011X: ~OC1REF OC1REF 11111100X: ~OC1REF OC1REF 11111101X: ~OC1REF OC1REF 11111110X: ~OC1REF OC1REF 11111111X: ~OC1REF OC1REF 从左到右依次为MOE, CC1E, CC1NE, CC1P, CC1NP, OIS1, OIS1N, OSSR, OSSI: CH1 CH1N OC1REF表示正常输出电平, ~表示取反,X表示don't care 从表格中可以看到一个事实:OSSI位没有任何作用! 并且,当输出总开关MOE=0时,输出端也能输出PWM波形,并非一定就是输出无效态电平! |
