L9733CNTR   与   L9733XPTR的区别

数据几乎一致，datasheet 上有一段Fault opertation 的区别如下， 具体选择哪一款看客户选择！

The fault diagnostic capability consists of one internal 16 bits shift register and 2 bits are used for each output. The diagnostic information is: no fault present, overcurrent, open load and short circuit.

For L9733XP all of the faults will be cleared on the rising edge of chip select if a valid DI byte is received.

For L9733CN the OVC register are cleared when the end of the diagnosis restart time Tres is reached or by the input signal (IN) in low state. The other faults are cleared on the rising edge of chip select if a valid DI byte is received.

故障诊断能力包括一个内部16位移位寄存器，每个输出使用2位。诊断信息为：无故障、过电流、开路和短路。

对于L9733XP，如果接收到有效的DI字节，将在芯片选择的上升沿清除所有故障。

对于L9733CN，当达到诊断重启时间Tres结束时，或输入信号（IN）处于低状态时，OVC寄存器被清除。如果接收到有效的DI字节，则在芯片选择的上升沿清除其他故障。
