FT260 LibFT260 unknown ftStatus 19

(1/1)

bludin:
In my test setup, FT260_I2CMaster_Read returns no data and ftStatus = 19 in about 20% of the cases.
Appendix C of AN_395_User_Guide_for_LibFT260.pdf only explains ftStatus 0-18 (17 being FT260_I2C_READ_FAIL).
What does 19 indicate?

see https://www.ftdichip.com/Support/Documents/AppNotes/AN_395_User_Guide_for_LibFT260.pdf

PS: the failure rate seems to be largely independent of the baud rate (100KHz, 400KHz, 1MHz), so bus capacitance is most likely not the problem.
