Condition (packet B) in present frame.
X. FIFO for storing data received from host in present frame
Y. FIFO for storing data for transmitting host in previous frame
Transaction format for Isochronous transfer type in receiving is given below.
Control flow
Isochronous transfer type is frame management. And data that is written to FIFO
Below are two conditions in FIFO of Isochronous receiving mode transferring
FIFO that is divided into two (packet A and packet B) conditions is whether X
X and Y conditions change one after the other by receiving SOF.
Below is control flow in the UDC when receiving OUT token.
The whole transaction is processed by hardware.
The UDC finishes normally by the above transaction.
The CPU takes back packet A’s data.
1. Token packet is received and address endpoint number error is confirmed, and it
2. Condition of status register is confirmed.
3. Data packet is received.
4. After last data has been transferred, and counted CRC is compared with
5. The transaction when SOF token from host is received is given below.

• INVALID condition: State return to IDLE.
Data is transferred from SIE into the UDC to packet A’s FIFO (X Condition).
• Change packet A’s FIFO from X Condition to Y Condition.
• Change packet B from Y Condition to X Condition, and clear data. Prepare
• Set frame number to frame register.
• Assert SOF and inform externally that frame is incremented.
• DATASET register set packet A bit and clear packet B bit arrangement
