NS16C2552: Confirmation with Datasheet (P.13) Description Even/Odd Parity Setting

Shinichi Inoue

Part Number: NS16C2552

Dear Specialists,

My customer is considering NS16C2552 and has questions.

I would be grateful if you could advise.

---

Regarding NS16C2552 Datasheet p13, Table 10. LCR (0x3) 

For the 4th bit of the LCR register, the Even / Odd parity setting does not match the description of the 5th bit of the same register.
Which is correct.


I think the 4th bit is a typo and 1 = Even parity and 0 = Odd Parity are correct.
Is it right?

I appreciate your great help in advance.

Best regards,

Shinichi

    Shinichi,

    Since this device is a copy of an older device the PC16552D, going off that old datasheet it says that for Bit 4. 0=Odd parity and 1 = Even parity. I would assume that that is true for the NS device.

    Thank you for catching this error and I will make sure that it gets fixed.

    Best,

    Chris
