Explanation:
Detailed explanation-1: -With an 8-bit data type, any data larger than 8 bits must be broken into 8-bit chunks before it is processed. The 8-bit WREG register is the most widely used register in the PIC micro controller. WREG stands for working register, as there is only one.
Detailed explanation-2: -The PIC16F877A-I/P is a 8-bit CMOS Flash-based Microcontroller.
Detailed explanation-3: -Usually, PIC16F877 devices have a 13-bit wide program counter that is capable of addressing 8K×14 bit program memory space.
Detailed explanation-4: -Capture mode: 1 = A TMR1 register capture occurred (must be cleared in software) Compare mode: PWM mode: 07-Feb-2011
