The 8051 has ____ 16 bit counter/timers
A
1
B
2
C
3
D
4
Explanation: 

Detailed explanation-1: -8051 has two timers Timer0 (T0) and Timer1 (T1), both are 16-bit wide. Since 8051 has 8-bit architecture, each of these is accessed by two separate 8-bit registers as shown in the figure below. These registers are used to load timer count.

Detailed explanation-2: -Detailed Solution. Microcontroller 8051 has two 16-bit timers and counters i.e. timer 0 and timer 1.

Detailed explanation-3: -8051 microcontroller is designed by Intel in 1981. It is an 8-bit microcontroller. It is built with 40 pins DIP (dual inline package), 4kb of ROM storage and 128 bytes of RAM storage, 2 16-bit timers. It consists of are four parallel 8-bit ports, which are programmable as well as addressable as per the requirement.
