IDMA Transfer of up to 75% of Bus Bandwidth
(see Note 5)
IDMA Transfer of up to 50% Of Bus Bandwidth
(see Note 5)
IDMA Transfer of up to 25% Of Bus Bandwidth
(see Note 5)
IDMA Transfer of up to 12.5% Of Bandwidth (see
Note 5)
Normal Operation (Software Reset OH)
Software Reset - Abort External Pending Cycles
Stop IDMA at the End of Current Transfer
Start (or Restart) IDMA Channel Transfer
NOTES:
1. When external pin DONE asserts, an interrupt request is generated.
2. The DONE bit is set in the CSR at the conclusion of data transfer.
3. Transfer occurs at maximum rate. Hardware signal DREQ is level sensitive.
4. Hardware signal DREQ is edge sensitive.
5. These percentages are valid only when bits 11 and 10 = 00.
