6.1 Legacy PS/2 Mouse Operating
6.1.1 Operating Mode
There are four operating modes in PS/2 mouse:
6.1.1.1 Reset Mode
In this mode a self-test is initiated during power-on or by a Reset command. After reset
signal, PS/2 mouse will
(1) Send completion code AA & ID code 00.
(2) Set default:
Sampling rate: 100 reports/s
Non-auto-speed
Stream mode
2 dot/count
Disable
6.1.1.2 Stream Mode
The maximum rate of transfer is the programmed sample rate.
Data report is transmitted if
(1) Switch is pressed
(2) Movement has been detect
6.1.1.3 Remote Mode
Data is transmitted only in response to a Read Data command.
6.1.1.4 Wrap Mode
Any byte of data sent by the system, except hex EC (Reset wrap mode) or hex FF
(Reset), is returned by eKM6211.

6.1.3 PS/2 Mouse Data Transmission
eKM6211 generates the clocking signal when sending data to and receiving data from
the system.
The system requests eKM6211 receive system data output by forcing the DATA line to
an inactive level and allowing CLK line to go to an active level.
Data transmission frame:
Bit
Function
1
Start bit ( always 0 )
2-9
Data bits ( D0 - D7 )
10
Parity bit ( odd parity )
11
Stop bit ( always 1 )
Data Output (data from eKM6211 to system):
If CLK is low (inhibit status), data is no transmission. If CLK is high and DATA is low
(request-to-send), data is updated. Data is received from the system and no
transmission are started by eKM6211 until CLK and DATA both high. If CLK and DATA
both are high, the transmission is ready. DATA is valid prior to the falling edge of CLK
and beyond the rising edge of CLK. During transmission, eKM6211 check for line
contention by checking for an inactive level on CLK at intervals not to exceed 100u sec.
4•
Product Specification (V1.0) 11.15.2003
(This specification is subject to change without further notice)
eKM6211
RF Mouse Rx Controller
Contention occurs when the system lowers CLK to inhibit eKM6211 output after
eKM6211 has started a transmission. If this occurs before the rising edge of the tenth
clock, eKM6211 internal store its data in its buffer and returns DATA and CLK to an
active level. If the contention does not occur by the tenth clock, the transmission is
complete. Following a transmission, the system inhibits eKM6211 by holding CLK low
until it can service the input or until the system receives a request to send a response
from eKM6211.
Data Input (from system to eKM6211):
The System first checks if eKM6211 is transmitting data. If eKM6211 is transmitting,
the system can override the output forcing CLK to an inactive level prior to the tenth
clock. If eKM6211 transmission is beyond the tenth clock, the system receives the
data. If eKM6211 is not transmitting or if the system choose to override the output, the
system force CLK to an inactive level for a period of not less than 100u sec while
preparing for output. When the system is ready to output start bit (0), it allows CLK go
to active level. If request-to-send is detected, eKM6211 clocks 11 bits. Following the
tenth clock, eKM6211 checks for an active level on the DATA line, and if found, force
DATA low, and clock once more. If occurs framing error, eKM6211 continue to clock
until DATA is high, then clocks the line control bit and request a Resend.
When the system sends out a command or data transmission that requires a response,
the system waits for eKM6211 to response before sending its next output.
6.1.4 PS/2 Mouse Error Handling
A Resend command (FE) following receipt of an invalid input or any input with
incorrect polarity.
If two invalid inputs are received in succession, an error code of hex (FC) is send to
the system.
The counter accumulators are cleared after receiving any command except
"Resend".
eKM6211 receives a Resend command (FE), it transmits its last packet of data.
In the stream mode "Resend" is received by eKM6211 following a 3-byte data
packet transmission to the system. eKM6211 resend the 3-byte data packet prior
to clearing the counter.
A response is sent within 25 ms if
The system requires a response
An error is detected in the transmission
If eKM6211 is in the stream mode:

eKM6211
RF Mouse Rx Controller
The system disables eKM6211 before issuing any command requiring a
response.
When a command requiring a response is issued by the system, another
command should not be issue until either the response is received or 25 ms
has passed.
6.1.5 PS/2 Mouse Commands Description
There are 16 valid commands that transmit between the system and eKM6211. The
"FA" code is always the first response to any valid input received from the system other
than a Set Wrap Mode or Resend command.
The following table lists the commands:

6.1.5.2 Resend (FE)
A
Any time eKM6211 receives an invalid command, it returns a Resend command to
the system.
B
When eKM6211 receives a Resend command, it retransmits its last packet of data.
If the last packet was a Resend command, it transmits the packet just prior to the
Resend command.
C
In stream mode, if a Resend command is received by eKM6211 immediately
following a 3-byte data packet transmission to the system.
6.1.5.3 Set Default (F6)
The command reinitializes all conditions to the power-on defaults.
6.1.5.4 Disable (F5)
This command is used in the stream mode to stop transmissions from eKM6211.
6.1.5.5 Enable (F4)
Begins transmissions, if in stream mode.
6.1.5.6 Set Sampling Rate (F3, XX)
In the stream mode, this command set the sampling rate to the value indicated by byte

6.1.5.7 Read Device Type (F2)
eKM6211 always echoes " FA, 00" following this command.
6.1.5.8 Set Remote Mode (F0)
Data values are reported only in response to a Read Data command.
6.1.5.9 Set Wrap Mode (EE)
Wrap mode remains until Reset (FF) or Reset Wrap Mode (EC) is received.
6.1.5.10 Reset Wrap Mode (EC)
eKM6211 returns to the previous mode of operation after receiving this command.
