This section describes how synchronization is achieved

Values of 252 to 255 are preserved for indicating start of trial/state information and in-between trial information stoppers:

• 252: indicates start of trial information
• 254: in between trial information to define trialinfo packages
• 253: end of trial information
• 255: start of state information

Note that due to preserved values, a trial information package maximum value is limited. For example, to encode the date first package would be first 2 digits of the year, second package the last 2 digits of the year, third package the month and fourth package the day. That way none of the packages reaches a value of over 100. Trial information is sent during INI (state 1), during the other states the stat value reflects the current state.
