When this pin is connected to VDD, then HT6513 is assigned
to operate under the microsoft mode only. If the pin is
connected to VSS, then HT6513 will operate under the mouse
system mode. If MS pin is “floating”, the HT6513 is on the
power on initiation mode.
TE ST

Pull-Low
For IC test only. The test pin must be connected to VSS, while
the chip is under normal usage.

The signal is sent by the mouse driver from the computer to
select the mode.
The HT6513 replies with the selected mode to the RXD line
after the pulse signal of the RTS line. RXD will send out “CD”H
code under the microsoft mode.

There are 7 or 8 bits in each data byte. Using parallel-in and
serial-out circuit, the data bytes are shifted out from bit 0
through the most significant bit. HT6513 will transmit the
data when the status of the three key-switches or the state of
the horizontal counter or vertical counter change.
