SA1 bus conflict

The only mention of the operation of the bus SA1 that I found is "SNES Development manual Book II".
Does anyone have any information about SA1, especially about the bus conflict, when SCPU and SA1 both access the same memory? I am interested: in what moment SA1 paused its core relative to the SYSCK signal of the SCPU?
