20.8.6 Macro Service Type A
(1) Operation
538
Data transfers are performed between buffer memory in the macro service channel and an SFR specified in the macro
service channel.
With type A, the data transfer direction can be selected as memory-to-SFR or SFR-to-memory.
Data transfers are performed the number of times set beforehand in the macro service counter. One macro service
processing transfers 8-bit or 16-bit data.
Type A macro service is useful when the amount of data to be transferred is small, as transfers can be performed at
high speed.
