IRQCLR Register
Name:
IRQCLR
Address:
0xFFFF000C
Default value:
0x00000000
Access:
Write only
IRQSTA
IRQSTA is a read-only register that provides the current
enabled IRQ source status (effectively a logic AND of the
IRQSIG and IRQEN bits). When set to 1, that source generates
an active IRQ request to the ARM7TDMI core. There is no
priority encoder or interrupt vector generation. This function is
implemented in software in a common interrupt handler
routine.
IRQSTA Register
Name:
IRQSTA
Address:
0xFFFF0000
Default value:
0x00000000
Access:
Read only
FAST INTERRUPT REQUEST (FIQ)
The fast interrupt request (FIQ) is the exception signal to enter
the FIQ mode of the processor. It is provided to service data
transfer or communication channel tasks with low latency. The
FIQ interface is identical to the IRQ interface and provides the
second level interrupt (highest priority). Four 32-bit registers
are dedicated to FIQ: FIQSIG, FIQEN, FIQCLR, and FIQSTA.
Bit 31 to Bit 1 of FIQSTA are logically OR’ed to create the FIQ
signal to the core and to Bit 0 of both the FIQ and IRQ registers
(FIQ source).
The logic for FIQEN and FIQCLR does not allow an interrupt
source to be enabled in both IRQ and FIQ masks. A bit set to 1
in FIQEN clears, as a side effect, the same bit in IRQEN.
Likewise, a bit set to 1 in IRQEN clears, as a side effect, the
same bit in FIQEN. An interrupt source can be disabled in both
IRQEN and FIQEN masks.
FIQSIG
FIQSIG reflects the status of the different FIQ sources. If a
peripheral generates an FIQ signal, the corresponding bit in
the FIQSIG is set; otherwise, it is cleared. The FIQSIG bits are
cleared when the interrupt in the particular peripheral is
cleared. All FIQ sources can be masked in the FIQEN MMR.
FIQSIG is read only.
FIQSIG Register
Name:
FIQSIG
Address:
0xFFFF0104
Default value:
Undefined
Access:
Read only
FIQEN
FIQEN provides the value of the current enable mask. When a
bit is set to 1, the corresponding source request is enabled
to create an FIQ exception. When a bit is set to 0, the corre-
sponding source request is disabled or masked, which does not
create an FIQ exception. The FIQEN register cannot be used to
disable an interrupt.
FIQEN Register
Name:
FIQEN
Address:
0xFFFF0108
Default value:
0x00000000
Access:
Read and write
FIQCLR
FIQCLR is a write-only register that allows the FIQEN register
to clear in order to mask an interrupt source. Each bit that is set
to 1 clears the corresponding bit in the FIQEN register without
affecting the remaining bits. The pair of registers, FIQEN and
FIQCLR, allows independent manipulation of the enable mask
without requiring an atomic read-modify-write.
FIQCLR Register
Name:
FIQCLR
Address:
0xFFFF010C
Default value:
0x00000000
Access:
Write only
FIQSTA
FIQSTA is a read-only register that provides the current enabled
FIQ source status (effectively a logic AND of the FIQSIG and
FIQEN bits). When set to 1, that source generates an active FIQ
request to the ARM7TDMI core. There is no priority encoder
or interrupt vector generation. This function is implemented in
software in a common interrupt handler routine.
