End the DMA transfer after the value of EPn_TCNT is “0” to decrement each transfer.
Cautions 1. Set this register when EPn_DMAEN = 0.
2. Setting this register to “0” is prohibited.
Be sure to set this register +1 value for the value of DMA transfer
count register DBC0 to DBC3.
3. The setting value of this register is reflected the counter BIN_TCNT
for bulk transfer of the bridge inside. And the value of BIN_TCNT is
“0”, EPn_TCN is “0”, too.
4. Update the value of the counter BIN_TCNT for bulk transfer is
stopped when forcibly terminated.
