Description
If this pin is connected to high level, the RXD can transmit data at
I 9600 baud rate. The RXD is transmitted at 1200 baud rate while
it is conected to low level or floating.
I
For IC test only. The test pin must be connected to VSS, while the
chip is under normal usage.
When this pin is connected to VDD , operation is under M+ mode. If
I
the pin is connected to VSS, then it will operate under the mouse
system mode. If MS pin is ²floating² , the product is under the
power-on initiation mode.
I Oscillator input pin
O Oscillator output pin
When a rising edge is sent to RTS the mouse will return a series ID
I code to identify the mouse mode. The RTS must be kept high while
the mouse is in normal operation.
O NMOS, Serial data output
I Negative power supply
Three key-switches have seven different combinations. Both
key-pressed and key-released signals will be sent accompanied
I with horizontal and vertical status. The status of the
key-switches, the values of horizontal or vertical counter will be
present at RXD pin.
Four photo-couplers/micro-switch signals denote UP, DOWN,
LEFT and RIGHT state. During the scanning period, as long as
I the photo-couplers/micro-switch change their states, the value of
vertical or horizontal counter will increase or decrease accord-
ingly.
I Positive power supply
