TLA2528: I can't find the STATS_EN bit mentioned in the text in the registers

Part Number: TLA2528

Page 15 of the datasheet (SBAS961A –MAY 2019–REVISED APRIL 2020) states:

If SCL stretching is not required during averaging, enable the statistics registers by setting STATS_EN to 1b and
initiate conversions by writing 1b to the CNVST bit. The OSR_DONE bit in the SYSTEM_STATUS register can
be polled to check the averaging completion status. When using the CNVST bit to initiate conversion, the result
can be read in the RECENT_CHx_LSB and RECENT_CHx_MSB registers.

I can't seem to find a STATS_EN bit in any of the register definitions.  For that matter I can't find the RECENT_CHx_LSB and RECENT_CHx_MSB registers either.

Do these registers/bits exist?  Is it possible to not use clock stretching when oversampling?

  • Hello,

    Apologies for the confusion, but this seem to be an error in the datasheet.

    This device is similar to another device, that does in fact have the STATS_EN register among others. please disregard this paragraph as a whole.

    As for the clock stretching. The device does this automatically. The device will hold down the clock until it is done converting, when it ready to receive more commands when it is done converting, it will release the clock.

    the user does not need to do anything aside from watch the clock and wait until it is released.

    Regards
