BQ40Z50-R1: SMBus: Are the Timing Requirements tables of the datasheet in right units ?

¨Hi,

If you see the 7.33 Timing Requirements: SMBus at the datasheet (SLUSCB3 –JULY 2015), you will find the tTIMEOUT = 25 to 35mS.
Comparing with Bq20z95 it's 1000 times slow. The Bq20z95 have the tTIMEOUT = 25 to 35uS.

Please help me to know which units are correct. Are the two ICs so differents? I have a problem to comunicate a host with the Bq40z50 and same host work well with Bq20z95. Both are SBS1.1 compliant. But searching the datasheets I found differents units in the Timming Requirements of the SMBus. Are the units ok? or miliseconds should be microseconds?

Thanks a lot in advance for the clarification!

Ricardo.
