7.3
dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
devices implement a total of 22 registers for the
interrupt controller:
• INTCON1
• INTCON2
• IFSx
• IECx
• IPCx
• INTTREG
7.3.1
Global interrupt control functions are controlled from
INTCON1 and INTCON2. INTCON1 contains the
Interrupt Nesting Disable bit (NSTDIS) 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.
7.3.2
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.
7.3.3
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.

7.3.4
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.
7.3.5
The INTTREG register contains the associated
interrupt vector number and the new CPU interrupt
priority level, which are latched into vector number
(VECNUM<6:0>) and Interrupt level bit (ILR<3:0>)
fields in the INTTREG register. The new interrupt
priority level is the priority of the pending interrupt.
The interrupt sources are assigned to the IFSx, IECx
and IPCx registers in the same sequence that they are
listed in
Interrupt 0) is shown as having vector number 8 and a
natural order priority of 0. Thus, the INT0IF bit is found
in IFS0<0>, the INT0IE bit in IEC0<0>, and the INT0IP
bits in the first position of IPC0 (IPC0<2:0>).
7.3.6
Although they are not specifically part of the interrupt
control hardware, two of the CPU Control registers
contain bits that control interrupt functionality.
• The CPU STATUS register, SR, contains the
• The CORCON register contains the IPL3 bit
All Interrupt registers are described in
through
IPL<2:0> bits (SR<7:5>). These bits indicate the
current CPU interrupt priority level. The user can
change the current CPU priority level by writing to
the IPL bits.
which, together with IPL<2:0>, also indicates the
current CPU priority level. IPL3 is a read-only bit
so that trap events cannot be masked by the user
software.
