+    (a) The timer for Sound DMA uses only 0

+  <Restrictions for H-DMA or DMA started with V-Blank>
+    These types of DMA can be operated on a maximum CPU cycle of 42 cycles.
+    Calculate the number of the transferable DMA count based on this 42 cycles and the access cycles of the destination and source.
+    For example, if both the CPU internal RAM --> VRAM have a one cycle access, then a 21 count DMA can occur.
+
+  
+  If RFU is used outside of these restrictions, problems, such as the loss of data caused by the failure of the AGB, as a clock slave, 
+  to notify that data has been received from the RFU, will occur.
+  When this problem occurs, the REQ callback will send a REQ_commandID=ID_CLOCK_SLAVE_MS_CHANGE_ERROR_BY_DMA_REQ notification.
+   (When using Link Manager, the LMAN call back will send a LMAN_msg=LMAN_MSG_CLOCK_SLAVE_MS_CHANGE_ERROR_BY_DMA notification.)
