the PS/2 device which generates the clock signal during data transmission.



Data Transmission from Device to the Controller

After  the  PS/2  mouse  receives  an  enabling  signal  at  stream  mode,  it  will  start  sending  out
displacement data, which consists of 33 bits. The frame data is cut into three sections and each of
them  contains  a  start  bit  (always  zero),  eight  data  bits  (with  LSB  first),  one  parity  check  bit  (odd
check), and one stop bit (always one).

The PS/2 controller samples the data line at the falling edge of the PS/2 clock signal. This is
implemented by a shift register, which consists of 33 bits.

easily be implemented using a shift register of 33 bits, but be cautious with the clock domain
crossing problem.



Data Transmission from the Controller to Device

When the PS/2 controller wants to transmit data to device, it first pulls the clock line low for more
than  one  clock  cycle  to  inhibit  the  current  transmission  process  or  to  indicate  the  start  of  a  new
transmission process, which is usually called as  inhibit state. It then pulls low the data line before
releasing the clock line. This is called the request state. The rising edge on the clock line formed by
the release action can also be used to indicate the sample time point as for a 'start bit. The device
will detect this succession and generates a clock sequence in less than 10ms time. The transmit data
consists  of  12bits,  one  start  bit  (as  explained  before),  eight  data  bits,  one  parity  check  bit  (odd
check),  one  stop  bit  (always  one),  and  one  acknowledge  bit  (always  zero).  After  sending  out  the
parity  check  bit,  the  controller  should  release  the  data  line,  and  the  device  will  detect  any  state
change on the data line in the next clock cycle. If there’s no change on the data line for one clock
cycle, the device will pull low the data line again as an acknowledgement which means that the data
is correctly received.

After the power on cycle of the PS/2 mouse, it enters into stream mode automatically and disable
data transmit unless an enabling instruction is received.

Figure 5-11

shows the waveform while

communication happening on two lines.
