ADSP-BF535 Blackfin Processor Hardware Reference
UARTx Transmit DMA Current Descriptor Pointer
Registers (UARTx_CURR_PTR_TX)
Figure 12-20
shows the UARTx Transmit DMA Current Descriptor
Pointer registers.
This register defines the lower 16 bits of the Current Descriptor
Pointer. The complete 32-bit address is created by combining this
value with the upper 16 bits from the DMA Descriptor Base
Pointer Register (
DMA_DBP
). For more information on the DMA
Descriptor Base Pointer Register, see
“Direct Memory Access” on
page 9-1
.
