NOTES:
1) DUE TO THE CYPRESS IMPLEMENTATION OF USB SUSPEND MODE SUPPORT, THE NRESET PIN OF THE HDNS-2000 MUST BE RESET
USING A LINE FROM THE CYPRESS CHIP. THE REASON FOR THIS IS THAT THE CYPRESS CHIP DOES NOT CONFIGURE THE PORT
INPUT PINS UNTIL AFTER IT HAS RECEIVED A BUS RESET FROM THE USB PORT. THE UNCONFIGURED INPUT PORT PINS PRESENT
A 16 K
PULLUP TO V
. IF A CAP IS USED ON NRESET (PIN 15), THIS PULLUP WILL RESULT IN THE HDNS-2000 SEEING A HIGH ON
THE MODE PIN AND POWERING UP IN THE PS/2.
2. THE QUADRATURE INPUT PINS OF THE CYPRESS PART MUST BE PROGRAMMED TO BE HI-Z, INSTEAD OF THE NORMAL CURRENT
PULLDOWNS. THIS ENSURES THAT THE HDNS-2000 WILL BE ABLE TO PULL THE QUADRATURE LINES HIGH OVER ALL
CONDITIONS OF VOLTAGE AND TEMPERATURE.

Note:
The 69.8 W resistor for bins K through N is determined by the absolute maximum rating of 50 mA for the HLMP-ED80.
The other resistor values for other bins will guarantee good signals with reduced power.
