(26) UF0 INT & DMARQ register (UF0IDR)
Remark
UF0IDR
Bit position
This register selects reporting via an interrupt request or starting DMA.
This register can be read or written in 8-bit units.
If data exists in either the UF0BO1 or UF0BO1 register, or if data can be written to the UF0BI1 or UF0BI2
register, this register selects whether it is reported to the FW by an interrupt request, or whether starting DMA
is requested. If starting DMA is requested, the DMA transfer mode can be selected according to the setting of
bits 0 and 1.
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.
Be sure to clear bits 3 and 2 to “0”. If they are set to 1, the operation is not guaranteed.
Caution If the target endpoint is not supported by the SET_INTERFACE request under DMA transfer,

the DMA request signal becomes inactive immediately, and the corresponding bit is
automatically cleared to 0 by hardware.

These bits enable (mask) a write DMA transfer request (DMA request signal for Endpoint
m) to the UF0BIn register. When these bits are set to 1, the DMA request signal for
Endpoint m becomes active while writing data can be acknowledged. If the DMA end
signal for Endpoint m is input (if the DMA controller issues TC), these bits are
automatically cleared to 0 by hardware. To continue DMA transfer, re-set these bits to 1
by FW.
These bits enable (mask) a read DMA transfer request (DMA request signal for Endpoint
x) to the UF0BOn register. When these bits are set to 1, the DMA request signal for
Endpoint x becomes active if the data to be read is prepared in the UF0BOn register. If
the DMA end signal for Endpoint x is input (if the DMA controller issues TC), these bits
are automatically cleared to 0 by hardware. They are also cleared to 0 when the
USBSPxB signal is active. To continue DMA transfer, re-set these bits to 1 by FW.

1: Enables active DMA request signal for Endpoint m (masks BKInDT interrupt).
0: Disables active DMA request signal for Endpoint m (default value).
1: Enables active DMA request signal for Endpoint x (masks BKOnDT interrupt).
0: Disables active DMA request signal for Endpoint x (default value).
