Timer0 Interrupt Flag (TMR0IF) bit is one of

the bit in Interrupt Control Register (INTCON)

Timer0 register will increase in every
instruction cycle

Timer0 register will increase from the loaded

value to the highest value.
(16-bit mode:0xFFFF or 8 bit-mode:0xFF)

Timer0 Interrupt flag will not raise (TMR0IF = 0)

as long as Timer0 did not overflow

Timer0 Interrupt flag is raised (TMR0IF = 1)
when Timer0 register is overflow and rolls over

(16-bit mode:0x0000 or 8 bit-mode:0x00)
