Re: Question about PXA27X processor system bus arbiter


Thanks for the immediate response
Well in the PXA27X manual for Bus Arbiter, there is a clause that
confuses me. It says that

" One final consideration in dynamically changing the ARBCNTL register
based on the current state of the system. For example, experimentation
may reveal that different DMA weights may be required, based on the
number of running channel. When the system enabled a new channel, the
ARBCNTL register can be written, resulting in an immediate reload of
the client counters"

Does it mean that we have to initialise the ARBCNTL register way
before any DMA channel is created or started?
