  1. For RGMII, transmit selected signals include: rgmiin_txd[3:0] and rgmiin_txctl.
  2. RGMII0 1000Mbps operation requires that the 4 data pins rgmii0_txd[3:0] and rgmii0_txctl have their board propagation delays matched within 50pS of rgmii0_txc
  3. RGMII1 1000Mbps operation requires that the 4 data pins rgmii1_txd[3:0] and rgmii1_txctl have their board propagation delays matched within 50pS of rgmii1_txc.

A. TXC is delayed internally before being driven to the rgmiin_txc pin. This internal delay is always enabled.
B. Data and control information is transmitted using both edges of the clocks. rgmiin_txd[3:0] carries data bits 3-0 on the rising edge of rgmiin_txc and data bits 7-4 on the falling edge of rgmiin_txc. Similarly, rgmiin_txctl carries TXEN on rising edge of rgmiin_txc and TXERR of falling edge of rgmiin_txc.

NOTE

To configure the desired Manual IO Timing Mode the user must follow the steps described in section "Manual IO Timing Modes" of the Device TRM.

The associated registers to configure are listed in the CFG REGISTER column. For more information please see the Control Module Chapter in the Device TRM.

Manual IO Timings Modes must be used to ensure some IO timings for GMAC. See Table 7-2Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 7-91Manual Functions Mapping for GMAC RGMII0 for a definition of the Manual modes.

Table 7-92 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.
