STATUS.SPEED Reflects 1000Mb/s speed, reporting fixed value of 10b.
PCS_LCTL.FSD Must be zero.
PCS_LCTL.Force Flow Control Must be zero
1
.
PCS_LCTL.FSV Must be set to 10b. Only 1000 Mb/s is supported in SerDes mode.
PCS_LCTL.FDV Ignored; duplex is set by priority resolution of PCS_ANDV and PCS_LPAB.
PCS_LCTL.AN TIMEOUT EN Must be 1b to enable auto-negotiation time-out.
CONNSW.ENRGSRC Must be 0b on 1000BASE-BX backplane, when source of the signal detect
indication is internal. When connected to an optical module and
SRDS_[n]_SIG_DET pin is connected to the module, should be 1b.
CTRL.ILOS If SRDS_[n]_SIG_DET pin connected to optical module, should be set according
to optical module polarity.
4.5.7.3.2 Auto-Negotiation Skipped (PCS_LCTL. AN ENABLE = 0b; CTRL.FRCSPD = 1b;
CTRL.FRCDPLX = 1b)
CTRL.FD Must be set to 1b. Only full duplex is supported in SerDes mode.
CTRL.SLU Must be set to 1b by software to enable communications to the SerDes.
CTRL.RFCE Must be 0b (No auto-negotiation).
CTRL.TFCE Must be 0b (No auto-negotiation).
CTRL.SPEED Must be set to 10b. Only 1000 Mb/s is supported in SerDes mode.
STATUS.FD Reflects the value written by software to CTRL.FD.
STATUS.LU Reflects whether the PCS is synchronized, qualified with CTRL.SLU (set to 1b).
STATUS.SPEED Reflects 1000 Mb/s speed, reporting fixed value of (10b).
PCS_LCTL.FSD Must be set to 1b by software to enable communications to the SerDes.
PCS_LCTL.Force Flow Control Must be set to 1b.
PCS_LCTL.FSV Must be set to 10b. Only 1000 Mb/s is supported in SerDes mode.
PCS_LCTL.FDV Must be set to 1b Only full duplex is supported in SerDes mode.
PCS_LCTL.AN TIMEOUT EN Must be 0b when auto-negotiation is disabled.
CONNSW.ENRGSRC Must be 0b on 1000BASE-BX backplane, when source of the signal detect
indication is internal. When connected to an optical module and
SRDS_[n]_SIG_DET pin is connected to the module, should be 1b.
CTRL.ILOS If SRDS_[n]_SIG_DET pin connected to optical module, should be set according
to optical module polarity.
4.5.7.4 MAC/SGMII Link Setup (CTRL_EXT.LINK_MODE = 10b)
Link setup procedures using an external SGMII interface mode:
4.5.7.4.1 Hardware Auto-Negotiation Enabled
(PCS_LCTL. AN ENABLE = 1b, CTRL.FRCDPLX = 0b, CTRL.FRCSPD = 0b)
CTRL.FD Ignored; duplex is set by priority resolution of PCS_ANDV and PCS_LPAB.
CTRL.SLU Must be set to 1b by software to enable communications to the SerDes.
