When I read the datesheet of IMX8mq about the CCM.
1.I can't understand the clock domain usage and why the same clock have 4 domain setting(for example CCM_PLL_CTRLn has setting1 ~setting3).The 4 domain settings of one clock are working at the same time?
2.What is the usage of PLL domain settings and CCGR domain settings?
em......NXP's datasheets are hard to understand!
Hi.
I also didn't understand that there are 4 domains.
"3.2.1.1 Features" of Resource Domain COntroller(RDC) in i.MX7D reference manual written as follews.
Assignment of cores, bus masters, peripherals, and memory regions to a resource domain.
Four of these ?
But it dosen't write which one is domain0.
Hi
for domain usage one can look at description in sect.5.1.5.7 Access control, sect.5.1.6.2 PLL Interface,
sect.5.2.4.2 Low power mode
i.MX 8M Dual/8M QuadLite/8M Quad Applications Processors Reference Manual
