Jabber Control Function
Figure 18 is a state diagram of the jabber control function.
An on-chip watchdog timer prevents the data terminal
equipment (DTE) from locking into a continuous
transmit mode. When a transmission exceeds the time
limit, the watchdog timer disables the transmit and
loopback functions, and activates the JABBER signal.
Before EtherCoupler can exit the jabber state, the transmit
data circuit must remain idle for between 0.25 and 0.75
seconds.
SQE TEST FUNCTION
The Transceiver supports the signal quality error (SQE)
test function as shown in Figure 19. After every
successful transmission on the 10BASE-T network,
EtherCoupler transmits the SQE signal to the DTE for
10
± 5 bit times over the internal CI circuit. Bit 1 of
Transceiver Status register BMPR15 reflects the status of
this SQE signal.
