Description
For TI use only (Default 3'b001)
1 = Enable pin switch feature using top level pin. Ignore MDIO software switch. Requires
setting PRTAD0_PIN_EN to high and setting PRTAD0_PIN_EN_SEL to control Rx data
switch.
0 = Disable pin switch feature. Only MDIO software switch is used (Default 1’b0)
Applicable when top level pin (PRTAD0) is assigned to control receive data switch source
input and if PRTAD0 is HIGH.
00 = Select LS input
01 = Select HS input(Default 2’b01)
10 = Reserved
11 = Reserved
Applicable when top level pin (PRTAD0) is assigned to control receive data switch source
input and if PRTAD0 is LOW.
00 = Select LS input
01 = Select HS input(Default 2’b01)
10 = Reserved
11 = Reserved
Applicable only in KR & KX modes. Selects data pattern to trigger OFF condition (Default
1’b0)
KR Mode:
1 = Local Fault (0x0100009c)
0 = IDLE (0x07 on all lanes)
KX Mode:
1 = Match DSR_OFF_CHAR specified in 1E.802E
0 = IDLE (Either /I1/ or /I2/)
Applicable only in KR & KX modes. Selects data pattern to trigger ON condition (Default
1’b0)
KR Mode:
1 = Local Fault (0x0100009c)
0 = IDLE (0x07 on all lanes)
KX Mode:
1 = Match DSR_ON_CHAR specified in 1E.802D
0 = IDLE (Either /I1/ or /I2/)
Applicable only in KR & KX modes. Selects data pattern to stuff the output during data
switching (Default 1’b0)
KR Mode:
1 = Local Fault (0x0100009c)
0 = IDLE (0x07 on all lanes)
KX Mode:
1 = /V/ Error propagation (K30.7)
0 = /I2/ (/K28.5/D16.2/)
For TI use only (Default 5’b00000)
