why 'find what writes to this address' can not pause the process in emulator?

[ycc688]

In the emulator, the 'find what writes to this address' feature is similar to a watchpoint in gdb, but why can't it pause the process?

[ycc688]

I want to pause the process to analyse the call stack using a watchpoint instead of a breakpoint

[cheat-engine]

in memory view at the bottom view (hexview) select the bytes to watch and choose data breakpoint, break on write or break on access
