PMIC READY of IMX6UL

Hi,

    We are designing a PCB with IMX6UL (MCIMX6G2CVM05AA) and PF3001 (MC32PF3001A7EP) PMIC. On muxing the pins of processor, there is a function ,"PMIC_READY"  under Clock Control Module (muxed to either JTAG_MOD or GPIO1_IO8) of processor.

Please find the below clarifications required for the signal.

Q1: Can you please explain the purpose/logic of the PMIC_READY signal.

Q2: Is PMIC_READY  a control  /indicator input signal to processor (from PMIC).

Q3: Can it be used for power on-off control logic with PMIC...?

 

   Not much details are available on the processor datasheet and reference manual, except for the register settings and mux configuration.

Please find the below  image (mux information) as available on Pg 178 of IMX6ULRM,for your reference.

 

PMIC_READY signal of IMX6UL

 

Thanks,

Uma
