INTCON REGISTER
The INTCON Register is a readable and writable
register which contains the various enable and ag bits
for the Timer0 overow and peripheral interrupts.
Figure 4-5 shows the bits for the INTCON register.
Note:
The T0IF will be set by the specied
condition even if the corresponding Inter-
rupt Enable Bit is cleared (interrupt
disabled) or the GIE bit is cleared (all
interrupts
disabled).
Before
enabling
interrupt, clear the interrupt ag, to ensure
that the program does not immediately
branch to the peripheral interrupt service
routine

T0IF: TMR0 overflow interrupt flag
1 = The TMR0 has overflowed
Must be cleared by software
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.
