condition is selected:
--press AddrBits to select "7 bits", "8 bits" or "10 bits";
--press Address to set the address value of I2C trigger. According to the setting
in AddrBits, the range can be from 0 to 0x7F, from 0 to 0xFF or from 0 to
0x3FF;
--press Direction to select "Read", "Write" or "R/W".

--press Data to set the data pattern of the current data bit to X, H or L;
--press Bytes to set the length of the data and the range is from 1 to 5;
--press AllBits to set the data pattern of all the data bits to the data pattern
specified in Data.
