EP03 set register (EP03CFG) [address 001916]

Bit name

Bit symbol

At reset

Function

H/W

S/W

In double buffer mode set the beginning address of buffer 1

area, using a relative value for the beginning address of

buffer 0.

b1b0

0 0 = 8 bytes

0 1 = 16 bytes

1 0 = 64 bytes

1 1 = 128 bytes

0 : Single buffer mode

1 : Double buffer mode

0 : Toggle bit clear disabled

1 : Writing “1” clears the toggle bit and DATA0 is used

as the next data PID.

“0” is always read when reading.

0 : Normal mode

1 : Continuous toggle mode (valid at Interrupt IN transfer)

0 : OUT (Data is received from the host.)

1 : IN (Data is transmitted to the host.)

b7b6

0 0 : Transfer disabled

0 1 : Bulk transfer

1 0 : Interrupt transfer

1 1 : Isochronous transfer

–: State remaining
