CY7C67200

IN Exception Flag (Bit 8)

The IN Exception Flag bit indicates when the device received an IN packet when armed for an OUT.

1:Received IN when armed for OUT

0:Received OUT when armed for OUT

Stall Flag (Bit 7)

The Stall Flag bit indicates that a Stall packet was sent to the host.

1:Stall packet was sent to the host

0:Stall packet was not sent

NAK Flag (Bit 6)

The NAK Flag bit indicates that a NAK packet was sent to the host.

1:NAK packet was sent to the host

0:NAK packet was not sent

Length Exception Flag (Bit 5)

The Length Exception Flag bit indicates the received data in the data stage of the last transaction does not equal the maximum Endpoint Count specified in the Device n Endpoint n Count register. A Length Exception can either mean an overflow or underflow and the Overflow and Underflow flags (bits 11 and 10, respectively) should be checked to determine which event occurred.

1:An overflow or underflow condition occurred

0:An overflow or underflow condition did not occur

Setup Flag (Bit 4)

The Setup Flag bit indicates that a setup packet was received. In device mode setup packets are stored at memory location 0x0300 for Device 1 and 0x0308 for Device 2. Setup packets are always accepted regardless of the Direction Select and Arm Enable bit settings as long as the Device n EP n Control register Enable bit is set.

1:Setup packet was received

0:Setup packet was not received

Sequence Flag (Bit 3)

The Sequence Flag bit indicates whether the last data toggle received was a DATA1 or a DATA0. This bit has no effect on receiving data packets; sequence checking must be handled in firmware.

1:DATA1 was received

0:DATA0 was received

Timeout Flag (Bit 2)

The Timeout Flag bit indicates whether a timeout condition occurred on the last transaction. On the device side, a timeout can occur if the device sends a data packet in response to an IN request but then does not receive a handshake packet in a predetermined time. It can also occur if the device does not receive the data stage of an OUT transfer in time.

1:Timeout occurred

0:Timeout condition did not occur

Error Flag (Bit 2)

The Error Flag bit is set if a CRC5 and CRC16 error occurs, or if an incorrect packet type is received. Overflow and Underflow are not considered errors and do not affect this bit.

1:Error occurred

0:Error did not occur

ACK Flag (Bit 0)

The ACK Flag bit indicates whether the last transaction was ACKed.

1:ACK occurred

0:ACK did not occur
