Answer 1

I don't understand your question

Answer 2

TCON and TMOD are the two function registers in 8051 micro controller.

TCON stands for Timer Control Register

TMOD stands for Timer Mode Register

1) TCON - It is an 8-bit controller where upper 4 bits control timer and counter and 4 lower bits control interrupts. The bits include TF1, TR1, TF0, TR0, IE1, IE0, IR0 AND IT0. These bits are used for software instructions.

2) TMOD - It is used to select timer. 4 bits control the operation of timer 0 and other 4 bits control timer 1. These include Gate, C/T, M1, M0, Gate, M1, M0.
