NOTES:
3. The bq2063 times out when any clock low exceeds TTIMEOUT
4. THIGH Max. is minimum bus idle time. SMBC = SMBD = 1 for t > 50 µs causes reset of any transaction involving bq2063 that is in
progress.
5. TLOW:SEXT is the cumulative time a slave device is allowed to extend the clock cycles in one message from initial start to the stop.
6. TLOW:MEXT is the cumulative time a master device is allowed to extend the clock cycles in one message from initial start to the stop.
