2.8 Jabber
A jabber condition occurs in 10 Mbits/s mode when the transmit packet
exceeds a predetermined length. When jabber is detected, the TP
transmit outputs are forced to the idle state, a collision is asserted, and
the JAB register bit is set in the MI serial port Status register.
Clearing the Jabber Disable (JAB_DIS) bit to 0 in the MI serial port
Configuration register disables the jabber function.
The jabber function is disabled in the 100 Mbits/s mode.
2.9 Reset
The device is reset when:
1.
V
DD
is applied to the device, or
The reset bit (RST) is set in the MI serial port Control register, or
2.
3.
The RESETn pin is asserted (LOW).
When reset occurs because of (1) or (2), an internal power-on reset
pulse is generated that resets all internal circuits, forces the MI serial port
bits to their default values, and latches in new values for the MI address.
After the power-on reset pulse has finished, the reset bit (RST) in the MI
serial port Control register is cleared and the device is ready for normal
operation.
When reset is initiated because of (3), the same procedure occurs except
the device stays in the reset state as long as the RESETn pin is held
LOW. The RESETn pin has an internal pullup to V
DD
. The device is
guaranteed to be ready for normal operation 50 ms after the reset
sequence is initiated.
