interrupt events by writing the appropriate values into the Inter-
rupt Assignment Registers (IAR).
Table 3
describes the inputs
into the SIC and the default mappings into the CEC.
Event Control
The ADSP-BF531/2/3 processor provides the user with a very
flexible mechanism to control the processing of events. In the
CEC, three registers are used to coordinate and control events.
Each register is 16 bits wide:
CEC Interrupt Latch Register (ILAT) – The ILAT register
indicates when events have been latched. The appropriate
bit is set when the processor has latched the event and
cleared when the event has been accepted into the system.
This register is updated automatically by the controller, but
it may be written only when its corresponding IMASK bit
is cleared.
CEC Interrupt Mask Register (IMASK) – The IMASK reg-
ister controls the masking and unmasking of individual
events. When a bit is set in the IMASK register, that event is
unmasked and will be processed by the CEC when asserted.
A cleared bit in the IMASK register masks the event, pre-
venting the processor from servicing the event even though
the event may be latched in the ILAT register. This register
may be read or written while in supervisor mode. (Note
that general-purpose interrupts can be globally enabled and
disabled with the STI and CLI instructions, respectively.)
CEC Interrupt Pending Register (IPEND) – The IPEND
register keeps track of all nested events. A set bit in the
IPEND register indicates the event is currently active or
nested at some level. This register is updated automatically
by the controller but may be read while in supervisor mode.
The SIC allows further control of event processing by providing
three 32-bit interrupt control and status registers. Each register
contains a bit corresponding to each of the peripheral interrupt
events shown in
Table 3 on Page 7
.
SIC Interrupt Mask Register (SIC_IMASK)– This register
controls the masking and unmasking of each peripheral
interrupt event. When a bit is set in the register, that
peripheral event is unmasked and will be processed by the
system when asserted. A cleared bit in the register masks
the peripheral event, preventing the processor from servic-
ing the event.
SIC Interrupt Status Register (SIC_ISR) – As multiple
peripherals can be mapped to a single event, this register
allows the software to determine which peripheral event
source triggered the interrupt. A set bit indicates the
peripheral is asserting the interrupt, and a cleared bit indi-
cates the peripheral is not asserting the event.
SIC Interrupt Wakeup Enable Register (SIC_IWR) – By
enabling the corresponding bit in this register, a peripheral
can be configured to wake up the processor, should the
core be idled when the event is generated. (

mation, see Dynamic Power Management on Page 11.
