Example 2. This more complicated example shows how packing is performed when the
source and destination sizes are the same—long word. This example also shows the entire
7-byte DHR in use. The source address is $00000000, and the destination address is
$20000003. The number of bytes to be transferred is 16.
IDMA channel 1 initialization required for this example:
Example 3. This example shows how packing operates when the source and destination
sizes are different. The source address is $00000002, and the destination address is
$20000002. The source size is long word, and the destination size is byte. The number of
bytes to be transferred is 8.
MOTOROLA
• ICCR = $0720. Recommended normal configuration.
• FCR1 = $89. Source function code is 1000; destination function code is 1001.
• SAPR1 = $00000000. Source address.
• DAPR1 = $20000003. Destination address.
• BCR1 = $00000010. Byte transfer count.
• CSR1 = $FF. Clear any CSR bits that are currently set.
• CMAR1 = $00. Disable interrupts for this example.
• CMR1 = $4701. Internal maximum transfer rate; starts IDMA.
—CSR1 = $FF. Clear any CSR bits that are currently set.
—CMAR1 = $00. Disable interrupts for this example.
—CMR1 = $47A1. Internal maximum transfer rate; starts IDMA.
