7.3
Interrupt Control and Status
Registers
The dsPIC33FJ12MC201/202 devices implement a
total of 22 registers for the interrupt controller:
INTCON1
INTCON2
IFSx
IECx
IPCx
INTTREG
7.3.1
INTCON1 AND INTCON2
Global interrupt control functions are controlled from
INTCON1 and INTCON2. INTCON1 contains the
Interrupt 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.
7.3.2
IFSx
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
IECx
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
IPCx
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
INTTREG
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 (ILR<3:0>) bit
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 Table 7-1. For example, the INT0 (External
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 positions of IPC0 (IPC0<2:0>).
7.3.6
STATUS/CONTROL REGISTERS
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
IPL<2:0> bits (SR<7:5>). These bits indicate the
current CPU interrupt priority level. The user
application can change the current CPU priority
level by writing to the IPL bits.
The CORCON register contains the IPL3 bit
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.
All Interrupt registers are described in Register 7-1
through Register 7-24 in the following pages.
