Hello NXP Semiconductor engineers

 

My customer asked us following I2C specification of NR3H2111.

Would you please confirm?

 

(1)

Could you show me whether NT3H2111 supports I2C software reset (Start-Cond and 9 clocks & Start-cond.) that is described in the attached file?

(2)

If the above is yes, could you show me how NT5T2111 acts when the clocks will short than 9 (eg. 8 clocks)?

(3)

After reading Chapter 9.3 of NT3H2111_2211 Datasheet(Rev.3.2), my customer believes that NT3H2111 will be reset every time Start conditions including repeated start are occurred when a condition of NFCS_I2C_RST_ON_OFF is set.

Is it true?

(4)

Do you have any description about a behavior of a condition NFCS_I2C_ON_OFF is cleared?

 

Best Regards, Shimura
