38 / 56 page  USB2642 DS00001578C-page 38 2014-2015 Microchip Technology Inc. 7.4.4.3 10Eh-114h: Combo LUN 2 Identifier String 7.4.4.4 115h-11Bh: Combo LUN 3 Identifier String 7.4.4.5 11Ch-122h: Combo LUN 4 Identifier String 7.4.4.6 123h-145h: Reserved 7.4.4.7 146h: Dynamic Number of Extended LUNs 7.4.4.8 147h-14Bh: LUN to Device Mapping Byte Name Description 6:0 CLUN2_ID_STR If the LUN to device mapping bytes have configured this LUN to be a combo LUNs, then these strings will be used to identify the LUN rather than the device identifier strings. Byte Name Description 6:0 CLUN3_ID_STR If the LUN to device mapping bytes have configured this LUN to be a combo LUNs, then these strings will be used to identify the LUN rather than the device identifier strings. Byte Name Description 6:0 CLUN4_ID_STR If the LUN to device mapping bytes have configured this LUN to be a combo LUNs, then these strings will be used to identify the LUN rather than the device identifier strings. Byte Name Description 27:0 rsvd Bit Name Description 7:0 DYN_NUM_ EXT_LUN These bytes are used to specify the number of LUNs the device exposes to the host. These bytes are also used for icon sharing by assigning more than one LUN to a single icon. This is used in applications where the device utilizes a combo socket and the OEM wishes to have only a single icon displayed for one or more interfaces. If this field is set to FF, the program assumes that you are using the default value and icons will be configured per the default configuration. Byte Name Description 4:0 LUN_DEV_MAP These bytes are used to specify the number of LUNs the device exposes to the host. These bytes are also used for icon sharing by assigning more than one LUN to a single icon. This is used in applications where the device utilizes a combo socket and the OEM wishes to have only a single icon displayed for one or more interfaces. If this field is set to FF, the program assumes that you are using the default value and icons will be configured per the default configuration. |
