configurable frame gap in di bits for 1st interval
This register specifies the 1
of di bit) for outgoing packets, where the 2
frame gap is fixed as 16 di bits (i.e. 32 bits). The minimum inter-
frame gate (IFG) defined in 802.3 is 96 bits (48 di bits). But for fast
transmission, many manufactures use smaller IFG (minimum is 32
bits) in practical. The allowable IFG_CFG value is 0..63 di bits.
Note that, TMAC only performs the carrier sense function during
the 1
duplex link, if an incoming packet arrives at the 2
collision with the ready-to-send outgoing packet will happen.
