Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | customRmbl | RW | 0 | Custom removable This bit controls the ability to write to the port removable bits. 0 = rmbl[3:0] are read only, and the values are loaded from the OTP ROM. 1 = rmbl[3:0] are R/W and can be loaded by EEPROM or written by SMBus. This bit can be written simultaneously with rmbl[3:0]. |
6:4 | RSVD | R | 0 | Reserved Read only, returns 0 when read |
3:0 | rmbl[3:0] | RW | X | Removable The bits in this field indicate whether a device attached to downstream ports 4 through 1 are removable or permanently attached. 0 = The device attached to the port is not removable. 1 = The device attached to the port is removable. Each bit corresponds directly to a downstream port n + 1, For example: rmbl0 corresponds to downstream port 1, rmbl1 corresponds to downstream port 2, and so on. This field is read only unless the customRmbl bit is set to 1. Otherwise, the value of this field reflects the inverted values of the OTP ROM non_rmb[3:0] field. |
