Document IMX8MMRM-i.MX 8M Mini Applications Processor Reference Manual, Rev 1, 03/2019 states that CCM_CLKO[2:1] can be connected to pads GPIO1_IO[14:15] (p. 1231). The signals are shown on page 262 as coming out of the CCM.
However, I cannot find the description for CCM_CLKO[2:1]. Could you let me know what this signal is? I am hoping it may be a clock output from the SoC.
