(7) External DMA request enable register (EXDRQEN)
Cautions 1. Assigning multiple DMA channels to the UDMARQ1/UDMAAK1 pin is prohibited (setting
The EXDRQEN register sets the DMA request to each DMA channel when connecting the external USB
device by using the UDMARQm/UDMAAKm pin (m = 0, 1).
This register can be read or written in 8-bit units.
Reset sets This register to 00H.

2. Assigning multiple DMA channels to the UDMARQ0/UDMAAK0 pin is prohibited (setting
3. Assigning both the UDMARQ1/UDMAAK1 pin and the UDMARQ0/UDMAAK0 pin to the
4. When using a DMA request from an external source by setting the EXDRQEN register, set
the RQ3EX1E, RQ2EX1E, RQ1EX1E, and RQ0EX1E bits to the UDMARQ1/UDMAAK1 pin at
the same time is prohibited).

the same time is prohibited).
same DMA channel is prohibited (setting the RQ3EX1E and RQ3EX0E, RQ2EX1E and
