Use Jlink to debug multicore system

I have an SoC which has dual Cortex-M7 CPUs, and CPU0/CPU1 is attached to the AHB Access Port0/1. When I connect to CPU0 using Jlink (JTAG interface), how can I read the registers of CPU1? Can I simply switch AP using APSEL and then access the CPU1’s resgisters using DCRSR and DCRDR?
