2.7.2 INTER-FUNCTION DELAY
By default, the inter-function delay is set to zero. Specify a value, ranging from 0 to 254,
to match the computer response time of the keyboard interface. Such delay time is
inserted between every function code (0x01 ~ 0x1F) being transmitted. The longer the
delay time is, the slower the transmission speed will be.
