Page 7, Pin Configuration continued:
- Pin Name PLED5 Description, all references to Transmit have been changed to Receive.
- Pin Name PLED4 Description, all references to Receive have been changed to Transmit.
- New reference to Pin #30 including Pin name, I/O and Description, has been added.
Page 8, Pin Description continued:
- 80 PQFP reference to Pin #30 has been deleted.
Page 9, Figure 1. 80220/80221 Block Diagram:
- Reference to RPTR
[1]
has been added.
Page 12, Table 1 80220 vs. 80221:
- Repeater Mode Pin has been added.
Page 13, Section 3.3.4 FBI - 100 Mbps:
- Paragraph 2 copy, ...RXD4, (4) CRS is asserted as long as the device is in the Link.... has been added.
Page 19, Section 3.9.4 TP Squelch, 10 Mbps:
- Reference to 75-250 nS has been changed to 50-250 nS.
Page 24, Section 3.13.9 Link Indication:
- Copy change, copy has been changed to...The PLED3 output is open drain with resistor pullup and can drive
an LED from VCC; The PLED0 output has both pullup and pulldown driver transistors in addition to a weak pullup
resistor, so it can drive an LED from either VCC or GND. Both PLED3 and PLED0 can also drive another digital
input. Refer...
Page 25, Section 3.15.2 10 Mbps:
- Copy change, copy has been changed to...If either 3 consecutive link pulses or one SOI pulse indicates incorrect
polarity on the TP receive input, ...
Section 3.16.3 Full Duplex Indication:
- Copy change, copy has been changed to...The PLED1 output has both pullup and pulldown driver transistors and
a weak pullup resistor, ...
Section 3.17.2 10/100 Mbps Indication:
- Copy change, copy has been changed to...The PLED0 output has both pullup and pulldown driver transistors
and a weak pullup resistor, ...
Section 3.18.1 Internal CRS Loopback:
- Copy change, copy has been changed to... in Link Fail State, and when the transmit disable bit is set in the MI
serial port Configuration 1 register. In 10 Mbps mode, ...
Page 26, Section 3.18.2 Diagnostic Loopback:
- Copy addition, copy has been changed to...do not change. Diagnostic loopback mode can not be enabled
when the FBI interface is selected.
Section 3.23 LED DRIVERS:
- First paragraph has changed to ...The PLED[5:2] outputs are open drain with a pullup resistor and can drive
LED's tied to VCC. The PLED[1:0] outputs have both pullup and pulldown driver transistors with a pullup resistor,
so PLED[1:0] can drive LED's tied to either VCC or GND.
Page 27, Table 5. LED Normal Function Definition:
- Columns PLED5 and PLED4 references to XMT and RCV have been switched, XMT is now RCV etc.
- Section 3.25 Repeater Mode has been added.
- Reference to Sections 3.25 have been changed to 3.26.
Page 28, Reference to Sections 3.25 have been changed to 3.26.
Table 7. MI Register Bit Type Definition:
- R/WS C Column, Write Cycle, Clears Itself After Operation Completed is now under Column Read Cycle.
