RF Keyboard Decoder

6.6.5 Read ID (Hex F2)

Responds with ACK.

Discontinues scanning.

Sends two ID Bytes. The second byte will be sent within 500 µS after first byte.

Resumes scanning.

6.6.6 Set Typematic Rate/Delay (Hex F3)

Responds ACK.

Receives rate/delay value byte.

Responds ACK.

Set rate/delay (* Note1)

Returns to previous scanning state.

NOTE

1 Repeat period = (8+A) x (2B) x 0.00417 seconds

A binary value of bits 2, 1, and 0

B binary value of bits 4 and 3

2 Delay = (C+1) x 250 milliseconds

C binary value of bits 6 and 5. Bit 7 is always 0

bit 4 ~ bit 0
