3.14.2.2.1. FGT Attribute Access Method Example 1

The followig example descibes the steps to eable ad disable seial loopback.
  1. To eable seial loopback:
    1. Asset RX eset.
    2. Wait fo RX eset ACK.
    3. Wite 0x6A040 to addess 0x9003C.

      6: data field fo seial loopback eable.

      A: optio field to equest sevice, ot set i eset ad set paametes.

      0: lae umbe field fo physical lae 0.

      40: opcode field fo seial loopback.

    4. Poll addess 0x90040 util bit 14 = 0 ad bit 15 = 1.
    5. Wite 0x62040 to addess 0x9003C.

      6: data field fo seial loopback eable.

      2: optio field to de-asset sevice equest, ot set i eset ad set paametes.

      0: lae umbe field fo physical lae 0.

      40: opcode field fo seial loopback.

    6. Poll addess 0x90040 util bit 14 = 0 ad bit 15 = 0.
    7. Deasset RX eset.
    8. Wait fo RX eset ACK deasset.
  2. To disable seial loopback:
    1. Asset RX eset.
    2. Wait fo RX eset ACK.
    3. Wite 0x0A040 to addess 0x9003C.

      0: data field fo seial loopback disable.

      A: optio field to equest sevice, ot set i eset ad set paametes.

      0: lae umbe field fo physical lae 0.

      40: opcode field fo seial loopback.

    4. Poll addess 0x90040 util bit 14 = 0 ad bit 15 = 1.
    5. Wite 0x02040 to addess 0x9003C.

      0: data field fo seial loopback disable.

      2: optio field to de-asset sevice equest, ot set i eset ad set paametes.

      0: lae umbe field fo physical lae 0.

      40: opcode field fo seial loopback.

    6. Poll addess 0x90040 util bit 14 = 0 ad bit 15 = 0.
    7. Deasset RX eset.
    8. Wait fo RX eset ACK deasset.
