eKM6211
RF Mouse Rx Controller
Preliminary
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.
(D) PS/2 Mouse Error Handling:
a. A Resend command (FE) following receipt of an invalid input or any input with incorrect
polarity.
b. If two invalid inputs are received in succession, an error code of hex (FC) is send to the system.
c. The counter accumulators are cleared after receiving any command except "Resend".
d. eKM6211 receives a Resend command (FE), it transmits its last packet of data.
e. 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.
f. A response is sent within 25 ms if
(a) The system requires a response
(b) An error is detected in the transmission
g. If eKM6211 is in the stream mode:
(a) The system disables eKM6211 before issuing any command requiring a response.
(b) 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.
