(31) UF0 data end register (UF0DEND)
UF0DEND
Remark
Bit position
This register reports the end of writing to the transmission system.
This register is write-only, in 8-bit units (however, bits 7 and 6 can be read and written). If this register is read, 00H
is read.
FW can start data transfer of the target endpoint by writing 1 to the corresponding bit of this register. The bit to
which 1 has been written is automatically cleared to 0. Writing 0 to the bit is invalid.
The related bits are invalid if each endpoint is not supported by the setting of the UF0EnIM register (n = 1, 3, 7)
and the current setting of the interface.

These bits specify whether toggling the FIFO is automatically executed if the FIFO on the
CPU side of the UF0BIn register becomes full as a result of DMA.
Set these bits to 1 to transmit the data of the UF0INT1 register. When these bits are set
to 1, the IT1NK bit is set to 1 and data transfer is executed.
If the ITR1C bit of the UF0FIC0 register is set to 1 and then these bits are set to 1
(counter of UF0INT1 register = 0 and the corresponding bit of the UF0EPS1 register = 1),
a Null packet (with a data length of 0) is transmitted.
If data exists in the UF0INT1 register and if these bits are set to 1 (counter of UF0INT1
register ≠ 0 and the corresponding bit of the UF0EPS0 register = 1), a short packet is
transmitted.
These bits are automatically controlled by hardware when the FIFO is full.
