LPC55s69 PLU配置

eefocus_3890704

需求：PIO1_28输入信号，PIO1_2和PIO1_3输出信号，希望输入输出信号相同，尽可能做到同步
问题：PLU配置完之后出来不了波形。具体配置如附件

PLU Config Tool v1.2配置代码如下：
/*
* This file was generated by the PLU Config Tool.
* 6 Inputs 26 LUTs 4 flip flops and 8 outputs */

/* LUT4 (LUT1) */
PLU->LUT[4].INP_MUX[0] = 0x00000003; /* IN3 (input) */
PLU->LUT[4].INP_MUX[1] = 0x0000003F; /* default */
PLU->LUT[4].INP_MUX[2] = 0x0000003F; /* default */
PLU->LUT[4].INP_MUX[3] = 0x0000003F; /* default */
PLU->LUT[4].INP_MUX[4] = 0x0000003F; /* default */
PLU->LUT_TRUTH[4] = 0xaaaaaaaa; /* LUT1 (LUT1) CUSTOM */

/* LUT5 (LUT2) */
PLU->LUT[5].INP_MUX[0] = 0x00000003; /* IN3 (input) */
PLU->LUT[5].INP_MUX[1] = 0x0000003F; /* default */
PLU->LUT[5].INP_MUX[2] = 0x0000003F; /* default */
PLU->LUT[5].INP_MUX[3] = 0x0000003F; /* default */
PLU->LUT[5].INP_MUX[4] = 0x0000003F; /* default */
PLU->LUT_TRUTH[5] = 0xaaaaaaaa; /* LUT2 (LUT2) CUSTOM */

PLU->OUTPUT_MUX[5] = 0x00000004; /* LUT4 (LUT1) -> output1 */
PLU->OUTPUT_MUX[6] = 0x00000005; /* LUT5 (LUT2) -> output2 */
