IDMA Channels
IDMA channel 1 initialization required for this example:
7.6.4.6.2 Single Address Mode (Flyby Transfers). Each IDMA channel can be indepen-
dently programmed to provide single address transfers. Figure 7-14 illustrates a transfer
from memory to a peripheral. The DHR is not used by the IDMA, since the transfer occurs
directly from a device to memory. This mode is often referred to as "flyby" mode because
the DHR is not used.
7-48
• ICCR = $0720. Recommended normal configuration.
• FCR1 = $89. Source function code is 1000; destination function code is 1001.
• SAPR1 = $00000002. Source address.
• DAPR1 = $20000002. Destination address.
• BCR1 = $00000008. Byte transfer count.
• CSR1 = $FF. Clear any CSR bits that are currently set.
• CMAR1 = $00. Disable interrupts for this example.
• CMR1 = $4711. Internal maximum transfer rate; starts IDMA.
