TPS25750: What's the the 'Data Bytes' size of 'DATA1' register

Won't the standard task response byte be read from DATA1? There is apparently one number 65 shown in the table.

Thanks.

I tried that when using 'I2Cr' to read the devices on I2Cm, the 'Byte Count' returned in Firgure 1-3 is 64. So if the first byte is the standard task response byte, then the remained the 'data' for user usage should be 64 - 1, this is conflict with Table 3-14. Or the standard response byte is not counted into the 'Byte Count', the 'Byte Count' and the '# Data Bytes' in Table 1-1 for 'DATA1' only count the bytes the user can use.

So, the max. bytes count we can read from DATA1 in an I2Cr task is 65, if take the task response byte into count.

Thanks.
