T0IF: TMR0 overflow interrupt flag
1 = The TMR0 has overflowed
0 = TMR0 did not overflow
T0IE: TMR0 interrupt enable bit
1 = Enables T0IF interrupt
0 = Disables T0IF interrupt
PEIE: Peripheral interrupt enable bit
1 = Enables all un-masked peripheral interrupts
0 = Disables all peripheral interrupts
GIE: Global interrupt enable
1 = Enables all un-masked interrupts
0 = Disables all interrupts
Reserved. This bit should be programmed as ‘0’. Use of this bit
as a general purpose read/write bit is not recommended, since
this may affect upward compatibility with future products.
