(28) UF0 DMA status 1 register (UF0DMS1)
UF0DMS1
Remark
Bit position
This register indicates the DMA status of Endpoint1 to Endpoint4.
This register is read-only, in 8-bit units.
The related bits are invalid if each endpoint is not supported by the setting of the UF0EnIM register (n = 1 to 4)
and the current setting of the interface.
Each bit is automatically cleared to 0 when this register is read. Even when this register is read, however, bits 4
and 3 of the UF0IS0 register are not cleared to 0.
SET_INTERFACE request, each bit is automatically cleared to 0 by hardware (however, the DMA_END interrupt
request and Short interrupt request are not cleared).

These bits indicate that the DMA end (TC) signal for Endpoint n becomes active and DMA
is stopped while a DMA read request is being issued from Endpoint n to memory.
These bits indicate that, although a DMA read request was being issued from Endpoint m
to memory, DMA has been stopped because the received data is a short packet and there
is no more data to be transferred.

1: DMA end signal for Endpoint n is active.
0: DMA end signal for Endpoint n is inactive (default value).
1: DMASTOP_EPm signal is active.
0: DMASTOP_EPm signal is inactive (default value).
