Functional Description
This section is divided into two subsections for your convenience and easy distinction.
Detailed PS/2 keyboard functions are described in Section 6.1, while that of USB
keyboard functions are discussed in Section 6.2.
6.1 PS/2 Keyboard Functional Description
The following describes the keyboard buffer, power-on reset and self test, input, output,
commands, and scan codes.
6.1.1 Keyboard Buffer
The keyboard buffer holds 16 bytes in a first-in-first-out order when the system receives
scan codes from the keyboard. The response codes and repeated codes are not
buffered. If the keystrokes generate a multiple-byte sequence, the entire sequence
must fit into the buffer, otherwise the keystroke is discarded and a buffer-overrun
condition occurs.
6.1.2 Power-on Reset and Self Test
The duration of keyboard Power-on-Reset (POR) is within 150 milliseconds to 2
seconds after the power is applied.
After executing POR, the keyboard executes a self test. The LEDs are light-on at the
beginning and tight-off at the end of the self test. The self test takes a minimum of 300
milliseconds and a maximum of 500 milliseconds. If the self test is successful, a
complete Code AA hex is sent to the system and the keyboard starts scanning. If the
self test fails, an error code is sent, then; the keyboard is disabled and waits for a
command from the system. The complete codes are sent within 450ms to 2.5s after
POR, and between 300ms to 500ms after a reset command is acknowledged.
6.1.3 Keyboard Data Output
When the keyboard is ready to send data to the system, it first checks the clock and
data lines. If either one is in the low state, data is stored in the keyboard buffer. If both
are in the high state, the keyboard starts clocking data out. Data is valid before the
trailing edge and after the leading edge of the clock pulse. During transmission, the
keyboard checks the clock line at least every 60 microseconds. If the system lowers
the clock lines before the leading edge of the 10th clock, the keyboard should stop
sending data, then buffers the data and returns the clock and data lines to a high state.
6.1.4 Keyboard Data Input
When the system is ready to send data to the keyboard, it first checks the clock line to
see if the keyboard is sending data. If the keyboard is not sending data or it is sending
data but has not reached the 10th clock, the system can inhibit the interface by forcing
the clock line to low for more than 60 microseconds and prepares to send data.

Product Specification (V1.0) 01.31.2013
(This specification is subject to change without further notice)
eKK8011S
USB and PS/2 Keyboard Encoder
The keyboard checks the clock line status at least every 5 milliseconds. If a system
Request to Send (RTS) is detected, the keyboard clocks 11 bits in. After the 10th bit,
the keyboard checks for a high state in the data line then pulls it low and clocks one
more bit to signal the system that data has been received. If data is low after the 10th
bit, it indicates a frame error. The keyboard should continue to count until the data line
goes high, then pulls it low and issues a Resend to the system.
6.1.5 Command from the System
The system can send commands to the keyboard any time of which the keyboard
needs to respond within 20 milliseconds, unless the system stops the keyboard from
outputting data during self test or reset execution. The following are the input
commands that the keyboard receives and actions that it needs to respond:
Set/Reset Status indicators (Hex ED)

followed by the high byte.
Keyboard Buffer Overrun (Hex 00 or FF)
If the keyboard buffer overflows, the overrun code will replace the last byte in the buffer.
If the keyboard is using Scan Code Set 1, the code is Hex FF. For Sets 2 and 3, the
code is Hex 00.
Resend (Hex FE)
When the keyboard receives an invalid input or any input with incorrect parity, the
RESEND command is sent.

6.1.7 Keyboard Scan Code Table
The keyboard contains three sets of scan code. The system defaults to Scan Code Set 2,
but can be switched to Set 1 or Set 3. The following tables show the key numbers and the
three scan code sets in hexadecimal values. All the keys are typematics except for the
pause key. When a key is pressed down, the Make Scan Code is sent to the system.
When the key is released, its Break Code is sent. If two or more keys are held down, only
the last pressed key repeats at the typematic rate. Typematic operation stops when the
last pressed key is released, even if the other keys are being released or some other keys
are still held down.
The following table shows three sets of scan code used in the keyboard.

6.2.2 LED Report for USB Keyboard
When one of the LED buttons (Num, Caps, Scroll) is pressed, the host issues a Setup
package (with a Set_Report request to Endpoint 0) and an Out package with 1 byte
data, which indicates the LED status. The format of the 1-byte data is –

6.2.3 USB Keyboard Scan Code
When the keys of HID Usage Page 07 are pressed, the scan codes are sent using
Endpoint 1. If the keys of HID Usage Page 01 and 0C are pressed, the scan codes are
sent using Endpoint 2.
When the host issues an IN packet to Endpoint 1 to receive data from the device and
the keys of HID Usage Page 07 are pressed, the device returns an 8 bytes to the host.
The 8 bytes are as follows:
