Problems with the FS26 enable regulator

[wuxianlong]

Hi，NXP

According to my understanding, the FS26 regulates through OTP configuration, and then the hardware automatically enables the output, such as LDO1 and LDO2. I see that the register M_REG_CTRL1 has the function of enabling LDO1. What is the role of this feature? In what circumstances is it used?

Best Regards,

OTP可以设定LDO是否开启，默认不动的情况下比方说OTP把她关掉了那么默认下就是关掉的，不过你也可以在上电以后通过SPI 设置你说的哪个寄存器去更改ON/OFF。
