14.3.10 USB Endpoint Data Register 0o (UEDR0o)
UEDR0o is a data register for endpoint 0 (for Control_out transfer). UEDR0o stores data received
from the host. The number of data items to be read must be the number of bytes specified by
UESZ0o.
When 1 byte is read from UEDR0o, UESZ0o is decremented by1.
UEDR0o is a byte register to which 4-byte address area is assigned. Accordingly, UEDR0o allows
the user to read 2-byte or 4-byte data continuously by word transfer or longword transfer.
14.3.11 USB Endpoint Data Register 3 (UEDR3)
UEDR3 is a data register for endpoint 3 (for Interrupt_in transfer). UEDR3 stores data to be sent to
the host. The number of data items to be written continuously must be the maximum packet size or
less.
UEDR3 is a byte register to which 4-byte address area is assigned. Accordingly, UEDR3 allows
the user to write 2-byte or 4-byte data continuously by word transfer or longword transfer. For
details, see section 2.9.4, Accessing Registers Containing Write-Only Bits.
14.3.12 USB Endpoint Data Register 1 (UEDR1)
UEDR1 is a data register for endpoint 1 (for Bulk_in transfer). UEDR1 stores data to be sent to the
host. The number of data items to be written continuously must be the maximum packet size or
less.
UEDR1 is a byte register to which 4-byte address area is assigned. Accordingly, UEDR1 allows
the user to write 2-byte or 4-byte data continuously by word transfer or longword transfer. For
details, see section 2.9.4, Accessing Registers Containing Write-Only Bits.
