5. Module: Interrupts
REGISTER 7-1:
FIGURE 1:
2003 Microchip Technology Inc.
The operation of the GIE/GIEH bit (INTCON<7>) is
clarified as follows: when the bit is cleared, all
interrupts are disabled. This is regardless of the
state of the IPEN bit (RCON<7>), the priority of the
interrupt, or whether or not the interrupt is
unmasked. This varies from the original descrip-
tion, in which clearing the bit when IPEN = 1 would
only disable high priority interrupts.
The seventh paragraph in Section 7.0 of the
Device Data Sheet (beginning “When an interrupt
is responded to....”) is amended by adding the fol-
lowing sentence to the end:
Low Priority Interrupt Generation
Peripheral Interrupt Enable bit
Peripheral Interrupt Priority bit
Peripheral Interrupt Flag bit

GIE/GIEH: Global Interrupt Enable bit
When IPEN (RCON<7>) = 0:
1 = Enables all unmasked interrupts
0 = Disables all interrupts
When IPEN (RCON<7>) = 1:
1 = Enables all high priority interrupts
0 = Disables all interrupts

“It is important to note, however, that clearing the
GIE/GIEH bit, regardless of the state of the IPEN
bit, will disable all interrupts.”
The changes to the bit descriptions in Register 7-1
in the Device Data Sheet are shown in the excerpt
below (changes in bold).
Also, the interrupt logic funnel shown in Figure 7-1
of the Device Data Sheet is amended with the
addition of a GIE/GIEH control line, as shown in
Figure 1 (new material in bold line).
