1.我使用的SDK版本：ti-processor-sdk-rtos-j721e-evm-08_01_00_13
2.我在MCU3_0中使用以下代码，我将GPIO口PIN_PRG0_PRU1_GPO1引脚复用为了UART5的TX功能。
想将GPIO ：PIN_PRG0_PRU1_GPO1拉低一段时间，来得到一段连续低的（0x00）信号，使其在UART5这边可以收到这段连续的拉低信号，但是操作无效，无法得到一段连续的拉低信号。
uint32_t tmp = *((volatile uint32_t *)0x0011C104); //save pre value
*((volatile uint32_t *)(0x00600014+0x50)) = 0x00010007; //config gpio
*((volatile uint32_t *)(0x00600014+0x50)) &= ~(1<<(64%32));//set gpio out
*((volatile uint32_t *)(0x00600014+0x50)) |= (1<<(64%32));//set gpio h
*((volatile uint32_t *)(0x00600014+0x50)) &= ~(1<<(64%32));//set gpio l
Osal_delay(1000);
*((volatile uint32_t *)(0x00600014+0x50)) |= (1<<(64%32));//set gpio h
*((volatile uint32_t *)0x0011C104) =tmp;//restore
帮忙看一下为什么无效，
