Answer 2

An alternate function of the port pin $P3.4$ in $8051$ is Timer 0.

What is Timer 0?

• Timers are a crucial part of any microcontroller.
• Timer 0 and timer 1 are two 16-bit counters/timers on the $8051$microcontrollers.

What is the alternate function port pin P3.4 in 8051?

• Timer 0 is the alternate function of the port pin $P3.4$.
• The external input pins $14$ and $15$ are for Timer 0 and Timer 1, respectively. They can be linked to a 16-bit timer or counter.
• The microcontroller counts the external clock pulses provided on pins $3.4(T0)$ and $3.5$ when used as counters$(T1)$

Hence, Timer 0 is an alternative function of the port pin$P3.4$ in the $8051$.
