Secondary Transmit Base Address
Only valid in switched-buffer DMA controller mode.
This bit field determines the base address of the secondary DMA
transmit buffer (buffer 2) in switched-buffer operation.
• If single-buffer operation is selected, this base address is "don’t care".
• If switched-buffer operation is selected (refer to register DMODE),
Note: If 16-bit bus operation is selected, the base address must be word
Only address TBADDR1(23:0) is used in this case.
transmission takes place based on both transmit buffers (TBADDR1
and TBADDR2). Data from these transmit buffers is sent alternating.
