- Responds ACK.

- Option byte =

01 : selects scan code set 1

02 : selects scan code set 2

03 : selects scan code set 3

- Returns to previous scanning rate.

Read ID (F2)

- Responds with ACK.

* Note 1

1. Repeat period = ( 8+A ) x ( 2^B) 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 Typematic rate ±20% bit 4~ bit 0 typematic rate ±20%
