PIC24FJ128GA FAMILY
6.3
The PIC24FJ128GA family devices implement a total
of 28 registers for the interrupt controller:
• INTCON1
• INTCON2
• IFS0 through IFS4
• IEC0 through IEC4
• IPC0 through IPC14, and IPC16
Global interrupt control functions are controlled from
INTCON1 and INTCON2. INTCON1 contains the Inter-
rupt Nesting Disable (NSTDIS) bit, as well as the
control and status flags for the processor trap sources.
The INTCON2 register controls the external interrupt
request signal behavior and the use of the Alternate
Interrupt Vector Table.
The IFS registers maintain all of the interrupt request
flags. Each source of interrupt has a status bit which is
set by the respective peripherals, or external signal,
and is cleared via software.
The IEC registers maintain all of the interrupt enable
bits. These control bits are used to individually enable
interrupts from the peripherals or external signals.
The IPC registers are used to set the interrupt priority
level for each source of interrupt. Each user interrupt
source can be assigned to one of eight priority levels.

Interrupt Control and Status
Registers
Advance Information
The interrupt sources are assigned to the IFSx, IECx
and IPCx registers in the same sequence that they are
listed in Table 6-2. For example, the INT0 (External
Interrupt 0) is shown as having a vector number and a
natural order priority of 0. Thus, the INT0IF status bit is
found in IFS0<0>, the enable bit in IEC0<0> and the
priority bits in the first position of IPC0 (IPC0<2:0>).
Although they are not specifically part of the interrupt
control hardware, two of the CPU control registers con-
tain bits that control interrupt functionality. The CPU
STATUS register (SR) contains the IPL2:IPL0 bits
(SR<7:5>). These indicate the current CPU interrupt
priority level. The user may change the current CPU
priority level by writing to the IPL bits.
The CORCON register contains the IPL3 bit, which
together with IPL2:IPL0, also indicates the current CPU
priority level. IPL3 is a read-only bit so that trap events
cannot be masked by the user software.
All interrupt registers are described in Register 6-1
through Register 6-30, in the following pages.
