(2) t_(HIGH) Max. is minimum bus idle time. SMBC = 1 for t > 50 ms causes reset of any transaction involving bq2084-V150 that is in
progress.
(3) t_(LOW:SEXT) is the cumulative time a slave device is allowed to extend the clock cycles in one message from initial start to the stop.
(4) t_(LOW:MEXT) is the cumulative time a master device is allowed to extend the clock cycles in one message from initial start to the stop.
