Function Descriptions
6.1 Decoder Buffer
The decoder will buffer 16 bytes in first-in-first-out order when the system is able to read scan codes from RF receiver module. The response codes and repeated codes will not be buffered. If receives a multiple-byte sequence, the entire sequence must fit into the buffer or the key data is discarded and a buffer-overrun condition occurs.

EKK6111 RF Keyboard Decoder
6.2 Power-on Reset and Self Test
The duration of the decoder Power-on-Reset (POR) should be within 150 milliseconds and 2 seconds after the power is applied to the decoder. After executing POR, the receiver executes a self test. The LEDs are turned in at the beginning and off at the end of the self test. The self test takes a minimum 300 milliseconds and a maximum 500 milliseconds. If the self test is successful, A completion code AA hex is sent to the system and the decoder starts read and decode the data from RF Rx module. If self test fails, and error code is sent, the decoder is disabled and waits for command from the system. The completion codes are sent between 450 milliseconds and 2.5 seconds after POR, and between 300 and 500 milliseconds after RESET command is acknowledged.
6.3 Decoder Data Output
When the decoder is ready to send data to the system, it first checks clock and data lines. If either one is in the low state, data is stored in the buffer. If both are in the high state, decoder starts clocking data out. Data will be valid before the trailing edge and after the leading edge of the clock pulse. During the transmissions the decoder checks the clock line at least 60 microseconds. If the system lowers the clock lines before leading edge of the 10th clock, the decoder should stop sending, then buffer the data and return clock and data to high state.
6.4 Decoder Data Input
When the system is ready to send data to the decoder, it first checks line to see if decoder is sending data. If decoder 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 low for more than 60 microseconds and prepares to send data. The decoder checks clock line status at least every 5 milliseconds. If a system Request to Send (RTS) is detected, the decoder clocks 11 bits in. After 10th bit, the decoder checks for high state in 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 decoder should continue to count until data line goes high, then pulls it low and issues a RESEND to the system.
6.5 Device ID
The EM83110A has support two device ID mode: Controllable ID mode: Using the 3 bits DIP switch to control the device ID. Random generate ID mode: Using the push bottom to entry the device ID set mode. The EM83110A will receives 10 seconds the new device ID after push bottom pressed. When PC reset, the device ID will recovery from EEPROM.

6.6 Command From the System

Keyboard Scan Code Table
The keyboard contains 3 scan code sets. The system defaults to scan set 2. but can be switched to set 1 or set 3 . The following tables show the key numbers and 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 key pressed repeats at the typematic rate. Typematic operation stops when the last pressed key is released, even if other keys are being released or some other keys are still held down. The following table shows three scan code sets used in the keyboard.
