您好:
我在使用sysconfig配置ESM System模块时将ERRORSTS管脚配置为PWM模式后,然后芯片在上电后需要大约84ms才能够正常发出方波信号,这个时间已经影响了外部SBC的运行,而ESMSYSTEM的初始化已经在程序运行的最开始,需要怎么配置才能让ERRORSTS管脚尽早的发出方波信号。

您好
If the error output pin is in PWM mode and when no error is detected pin toggles according to programmable
MMR widths for high and low periods. When an error occurs, the error pin stops toggling and remains constant
until the error is cleared. An external Power Management Integrated Circuits (PMIC) that is detecting the
PWM toggles can identify the error if the pin stops toggling. The periods must be programmed considering the
expectation of the external PMIC.
根据着部分说明调节对应的MMR和时钟进行优化,详细参考TRM www.ti.com.cn/.../SPRUJ79
