Debug Support
)
Likewise, the following BDM sequence is needed to write an accumulator register:
BdmWriteACCn (
)
Additionally, it is required that writes to the accumulator extension registers be performed after the
corresponding accumulators are updated. This is needed since a write to any accumulator alters the
contents of the corresponding extension register.
