Question about MS8607 Humidity Resolution Options

[Crowley723]

I am in the process of attempting to create a smaller port of the MS8607 module to use with Micro Python on an ESP8266 (I have been unable to find a compatible existing module)

While analyzing the existing module and referencing a datasheet for the MS8607-02BA01 PHT Combination Sensor I discovered that (at least in the datasheet I have) that it doesn't have any humidity options other than OSR_2048 - 0x81. Is this the case?
I cant find any reference in the entire datasheet I have to any functions/resolutions/sampling rates that reference (0x01, 0x80, 0x00).

It is possible the datasheet represents a different MS8607 module but I thought I may as well ask.
Any information that could be provided would be much appreciated.

for reference, this is on line 95 of adafruit_ms8607.py:

HumidityResolution.add_values(
    (
        ("OSR_256", 0x01, 8, 0.003),
        ("OSR_1024", 0x80, 10, 0.005),
        ("OSR_2048", 0x81, 11, 0.009),
        ("OSR_4096", 0x00, 12, 0.016),
    )

See page 8 of the datasheet here regarding the user register settings. It actually looks like they may be defined incorrectly here in this library.

Hello was taking a look at this, Humidity is compared with a mask here and that is why gets a little confusing comparing to the datasheet values.

Adafruit_CircuitPython_MS8607/adafruit_ms8607.py

Line 379 in 77b5038

reg_value |= resolution & _MS8607_HUM_USR_REG_RESOLUTION_MASK

HumidityResolution.add_values(
    (
        ("OSR_256", 0x01, 8, 0.003),
        ("OSR_1024", 0x80, 10, 0.005),
        ("OSR_2048", 0x81, 11, 0.009),
        ("OSR_4096", 0x00, 12, 0.016),
    )
)

Bit 7	Bit 0	Resolution	Calculation	Result
0	0	4096	0x00 & 0b10000001	0......0
0	1	2048	0x01 & 0b10000001	1......1
1	0	1024	0x80 & 0b10000001	1......0
1	1	256	0x81 & 0b10000001	1......1

I do have the Sensor so I an take a look to see if this is indeed the case, and make a PR. let me know, thanks
