5.8 Erratta / Notes
4 April 2003 - The QT60xx5 version 1.05 datasheet erroneously showed negative recalibration timeouts in the range from
1..255 seconds. The correct range is 0.1..25.5 seconds. From datasheet version 1.06 on, this document change has been
made. The devices themselves are not affected.
5.7 Timing Limitations
The device requires processing time between bursts, as well
as time to handle communications with the host. With short
burst spacings, long burst lengths, and long intra-burst pulse
spacings, the device can simply run out of available
processing time. When this happens, burst timing and host
communications slow down and become erratic.
It is important that burst spacings be verified on an
oscilloscope with an actual keymatrix during development to
be certain that the device timings are preserved and are
constant. If not, the burst length and/or pulse spacing should
be reduced.
