The non-Combo chips remain at V1.0.9.6 as they are not affected by the changes. The following changes have been made to the chips: ¥ Moved sending mouse data to the 1msec interrupt. This increases the maximum trackable speed for trackballs. It was also necessary because some host controllers do send overlapping reset commands to keyboard and mouse which could block the mouse function. ¥ Added delay before starting to generate clock on PS/2 mouse for host to device transfers. Some host controllers seem not to be able to remember that they released the clock and do not transfer data properly if the clocking starts too soon. ¥ Added checking for continuous data low condition for PS/2 keyboard and mouse receive functions. This reduces problems with spikes on the data line. ¥ Optimized serial mouse code for memory use. ¥ Added a "wait for serial to complete" at the IIC read routine of Flex, Operator, and Commander Combo controllers. Entering the IIC routines while the serial mouse did send data could corrupt the timing of the transmitted data. This affects only the Combo (mouse and keyboard) controllers: KWCOFX KWCOOP KWCOCM KWCVFX KWCVOP KWCVCM And customer specific derivateives of those chips. If you are using KeyWarrior Combo in any variant and make use of the PS/2 and/or serial port please make sure to qualify this new version for your production. The USB and ADB port are not affected by the changes. ################################################### Disclaimer Trademarks mentioned in this newsletter are the properties of their respective owners.
