Question

In mode 2, the baud rate depends only on

(a) SMOD bit

(b) SCON bit

(c) Oscillator clock frequency

(d) SMOD bit and oscillator clock frequency

I got this question by my college director while I was bunking the class.

I'm obligated to ask this question of Serial Communication Unit topic in chapter Microcontroller 8051 of Microprocessor

Answer 1

The correct choice is (d) SMOD bit and oscillator clock frequency

To explain I would say: In mode 2, the baud rate depends only on SMOD bit and oscillator clock frequency.
