S/W

IN : Transmit byte number bit

OUT : Receive byte number bit

Not used

–: State remaining

Single buffer mode: Set the transmitting byte number.

Double buffer mode : Set the transmitting byte number

of buffer 0.

Single buffer mode : The received byte number is

automatically set.

Double buffer mode : The received byte number of buffer 0

is automatically set.

Write “0” when writing.

“0” is read when reading.

Function

H/W

S/W

USB function/Endpoint 3 buffer 0

ready interrupt bit

USB function/Endpoint 3 buffer 1

ready interrupt bit

USB function/Endpoint 3 error

interrupt bit

Not used

0 : No interrupt request issued

1 : Interrupt request issued

This bit is set to “1” when the buffer 0 is ready state

(enabled to be read/written) on USB function/Endpoint 3.

“0” can be set by software, but “1” cannot be set.

0 : No interrupt request issued

1 : Interrupt request issued

In single buffer mode this bit is invalid.

This bit is set to “1” when the buffer 1 is ready state

(enabled to be read/written) on USB function/Endpoint 3

in double buffer mode.

“0” can be set by software, but “1” cannot be set.

0 : No interrupt request issued

1 : Interrupt request issued

This bit is set to “1” when STALL response occurs on

USB function/Endpoint 3.

“0” can be set by software, but “1” cannot be set.

Write “0” when writing.

“0” is read when reading.
