ICS1893Y-10 Rev F 1/20/04
This section first discusses reset operations in general and then specific ways in which the ICS1893Y-10
can be configured for various reset options.
The following reset operations apply to all the specific ways in which the ICS1893Y-10 can be reset, which
are discussed in
When the ICS1893Y-10 enters a reset condition (either through hardware, power-on reset, or software), it
does the following:
1. Isolates the MAC/Repeater Interface input pins
2. Drives all MAC/Repeater Interface output pins low
3. Tri-states the signals on its Twisted-Pair Transmit pins (TP_TXP and TP_TXN)
4. Initializes all its internal modules and state machines to their default states
5. Enters the power-down state
6. Initializes all internal latching low (LL), latching high (LH), and latching maximum (LMX) Management
When the ICS1893Y-10 exits a reset condition, it does the following:
1. Exits the power-down state
2. Latches the Serial Management Port Address of the ICS1893Y-10 into the Extended Control Register,
3. Enables all its internal modules and state machines
4. Sets all Management Register bits to either (1) their default values or (2) the values specified by their
5. Enables the Twisted-Pair Transmit pins (TP_TXP and TP_TXN)
6. Resynchronizes both its Transmit and Receive Phase-Locked Loops, which provide its transmit clock
7. Releases all MAC/Repeater Interface pins, which takes a maximum of 640 ns after the reset condition
As with the ICS189X products, the ICS1893Y-10 reset design supports ‘hot insertion’ of its MII. (That is, the
ICS1893Y-10 can connect its MAC/Repeater Interface to a MAC/repeater while power is already applied to
the MAC/repeater.)
