Table 2
shows the ID and priority at reset of each of the
peripheral interrupts. To assign the peripheral interrupts a
different priority, applications write the new priority to their
corresponding control bits (determined by their ID) in the
Interrupt Priority Control register. The peripheral inter-
rupt’s position in the IMASK and IRPTL register and its
vector address depend on its priority level, as shown in
Table 1
. Because the IMASK and IRPTL registers are
limited to 16 bits, any peripheral interrupts assigned a
priority level of 11 are aliased to the lowest priority bit
position (15) in these registers and share vector address
0x00 01E0.
Interrupt routines can either be nested with higher priority
interrupts taking precedence or processed sequentially.
Interrupts can be masked or unmasked with the IMASK
register. Individual interrupt requests are logically ANDed
with the bits in IMASK; the highest priority unmasked
interrupt is then selected. The emulation, power-down, and
reset interrupts are nonmaskable with the IMASK register,
but software can use the DIS INT instruction to mask the
power-down interrupt.
The Interrupt Control (ICNTL) register controls interrupt
nesting and enables or disables interrupts globally. The gen-
eral-purpose Programmable Flag (PFx) pins can be
configured as outputs, can implement software interrupts,
and (as inputs) can implement hardware interrupts. Pro-
grammable Flag pin interrupts can be configured for
level-sensitive, single edge-sensitive, or dual edge-
sensitive operation.
The IRPTL register is used to force and clear interrupts.
On-chip stacks preserve the processor status and are auto-
matically maintained during interrupt handling. To support
interrupt, loop, and subroutine nesting, the PC stack is
33 levels deep, the loop stack is eight levels deep, and the
status stack is 16 levels deep. To prevent stack overflow, the

These interrupt vectors start at address 0x10000 when the DSP is in
“no-boot”, run-form-external memory mode.
