Multichannel RAM Operation Example
The multichannel RAM operation example is shown below.
This example shows the case that an external MCU uses the
38K0 group as a peripheral LSI (USB controller).
The following explains that the external MCU reads out the data
which is received via the USB.
The data which is received via the USB is written into the multi-
channel RAM.
Receive completion is propagated to the CPU.
The external bus interface is activated owing to the CPU.
(1) The external bus interface sets the data which is read from
the multichannel RAM into the internal data buffer.
(2) The external MCU reads out the data bus buffer of the exter-
nal bus interface.
(3) The above operation is repeated by the number of the re-
ceived bytes. After that, the data transfer is completed.
