JAJSOK5Q March 2011 – March 2024 TUSB7320 , TUSB7340
PRODUCTION DATA
This register is used to control the de-emphasis and transmit swing settings for each of the USB 3.0 ports when the default setting is overridden through the Custom PHY Transmit/Receive Control Register. This register is reset by a PCI Express reset (PERST#), a GRST#, or the internally-generated power-on-reset.
PCI register offset: E4h
Register type: Read/Write
Default value: 0000 0000h

BIT | FIELD NAME | ACCESS | DESCRIPTION |
---|---|---|---|
31:28 | PORT4_SWING(1) | rw | Port 4 Swing. When the PORT4_SWING_OV bit is set to 1, these bits are used to set the output swing for port 4. For details on the behavior of the swing signals refer to Table 6-1. For the TUSB7320 Port 4 is not present and these bits have no effect. |
27:24 | PORT4_DE(1) | rw | Port 4 De-emphasis. When the PORT4_DE_OV bit is set to 1, these bits are used to set the de-emphasis value for port 4. For details on the behavior of the swing signals refer to Table 6-2. For the TUSB7320 Port 4 is not present and these bits have no effect. |
23:20 | PORT3_SWING(1) | rw | Port 3 Swing. When the PORT3_SWING_OV bit is set to 1 these bits are used to set the output swing for port 3. For details on the behavior of the swing signals refer to Table 6-1. For the TUSB7320 Port 3 is not present and these bits have no effect. |
19:16 | PORT3_DE(1) | rw | Port 3 De-emphasis. When the PORT3_DE_OV bit is set to 1 these bits are used to set the de-emphasis value for port 3. For details on the behavior of the swing signals refer to Table 6-2. For the TUSB7320 Port 3 is not present and these bits have no effect. |
15:12 | PORT2_SWING(1) | rw | Port 2 Swing. When the PORT2_SWING_OV bit is set to 1, these bits are used to set the output swing for port 2.For details on the behavior of the swing signals refer to Table 6-1. |
11:8 | PORT2_DE(1) | rw | Port 2 De-emphasis. When the PORT2_DE_OV bit is set to 1 these bits are used to set the de-emphasis value for port 2. For details on the behavior of the swing signals refer to Table 6-2. |
7:4 | PORT1_SWING(1) | rw | Port 1 Swing. When the PORT1_SWING_OV bit is set to 1, these bits are used to set the output swing for port 1. For details on the behavior of the swing signals refer to Table 6-1. |
3:0 | PORT1_DE(1) | rw | Port 1 De-emphasis. When the PORT1_DE_OV bit is set to 1, these bits are used to set the de-emphasis value for port 1. For details on the behavior of the swing signals refer to Table 6-2. |
