// Restrictions When Using RFU
//
// --------------------------------------------------------------------------
/*
The following restrictions apply when using RFU.
<Restrictions for Direct Sound>
(a) The timer for Sound DMA uses only 0
(b) The prescaler for the timer count for the Sound DMA uses 59.5 ns.
(c) The sound sampling rate is Max36.314KHz.
<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.)
