BQ28Z610-R1: I2C speed. Default

Part Number: BQ28Z610-R1

From SLUUC81 Section 12.2.30

XL (Bit 22): 400-kHz mode
1 = Active
0 = Inactive

From SLUUC81 Section 12.3.1

Bit 3: XL—Enable 400-kHz COM mode
0 = Normal bus speed (default)
1 = 400-kHz bus speed (slave mode)

Slave mode maximum speed is clearly indicated in the datasheet for the part.

Question: What is Normal bus speed (default) ?

Given that SLUUC81 refers to SMbus I am hoping that it is 100 kHz but I can't find it stated anywhere.
