H0~H7: The values of horizontal counter.
V0~V7: The values of vertical counter.
EH0~E H7: The values of extra horizontal counter.
E V0~E V7: The values of extra vertical counter.
Microsoft system mode
In the microsoft mode only 3 words are trans-
mitted with each word divided into one start
bit, seven data bits and two stop bits. Note that
only 2 switch operation is available with the
“M” switch being redundant in this mode. The
“L” and “R” switch status together with the two
most significant bits of both vertical and hori-
zontal counters are transferred in this first
word. The second and third word represent the
horizontal and vertical counters respectively.
Note that this vertical data is recorded in 2’s
complement format.

Function Descriptions
Mouse system mode
Any change of state of the mouse key-switches
or photo-couplers will be detected by the
HT6513 and transmitted over the RS-232C.
The mouse system protocol will send five words
at a 1200 baud rate with each word containing
10 bits, one start bit, one stop bit and eight data
bits. The first, second and third words corre-
spond to key switch-status, horizontal counter
and vertical counter respectively. The auto-
speed sensing circuits ensure detection of
higher mouse speeds resulting in the use of the
4th and 5th words for extra horizontal and ver-
tical overflow counts respectively. For lower
mouse speeds the 4th and 5th words remain at
zero.
