Description
PAUSE Frame Usage with TIME = 0 Enable/Lost
Carrier Error Detection Enable.
PAUSE Frame Usage with TIME = 0 Enable (In full-
duplex mode)
0: Control of a PAUSE frame whose TIME parameter
1: Control of a PAUSE frame whose TIME parameter
Lost carrier Error Detection Enable (In half-duplex
0: A lost carrier error is checked during frame
1: A lost carrier error is not checked during frame
Lost carrier error detection can be enabled only when
the time period from the EX_TX_EN signal activation
(high-active) to the ET_CRS = 1 detection is 63BT* or
less.
If the time period from the EX_TX_EN signal activation
(high-active) to the ET_CRS = 1 detection is greater
than 63BT*, or if the ET_CRS signal timing is
undefined, this bit should not be cleared to 0.
Note*: 1BT = 1ns (1000Mbps), 1BT = 10ns (100bps),
PAUSE Frame Receive Mode
0: PAUSE frame is not transferred to E-DMAC
1: PAUSE frame is transferred to E-DMAC

The next frame is not transmitted until the time
specified by the Timer value has elapsed. If a
PAUSE frame whose time specified by the Timer
value is 0 is received, that PAUSE frame is
discarded.
value is 0 is enabled.
When the data size in the receive FIFO becomes
smaller than the FCFTR setting before the time
specified by the Timer value elapses, an automatic
PAUSE frame with a Timer value of 0 is transmitted.
On receiving a PAUSE frame with a Timer value of 0,
the transmission wait state is canceled.
