20.8.7 Macro Service Type B
(1) Operation
Data transfers are performed between a data area in memory and an SFR specified by the macro service channel.
With type B, 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.
This type of macro service is macro service type A for general purposes and is ideal for processing a large amount
of data because up to 64 K bytes of data buffer area when 8-bit data is transferred or 1 M bytes of data buffer area
when 16-bit data is transferred can be set in any address space.
