ST25R3918 I2C Question regarding BSS

[danyavin]

hello, im designing an RFID board, using the ST25R3918, no where in the datasheet have i been able to find what to do with BSS/MOSI (float, pull up or down). I saw that BSS is used with I2C regarding transparent mode, but that's not needed for my project
thank you

Hi danyavin,

Better to tie BSS and MOSI to defined values to avoid additional current. I am investigating whether one or the other level for BSS would be preferred. For MOSI it is really a don't care if GND or VDD_IO.

thank you very much, would love an update

Hi,

with my current view it is also a don't care whether you tie BSS to GND or VDD_IO.
