Interrupt Registers
B-16 ADSP-21368 SHARC Processor Hardware Reference
9IRQ1I IRQ1 Hardware Interrupt. Indicates if an IRQ1I is latched and is
pending (if set, = 1), or no IRQ1I is pending (if cleared, = 0). An
IRQ1I occurs when an external device asserts the FLAG1 pin config-
ured as IRQ1
.
10 IRQ0I IRQ0 Hardware Interrupt. Indicates if an IRQ0I is latched and is
pending (if set, = 1), or no IRQ0I is pending (if cleared, = 0). An
IRQ0I occurs when an external device asserts the FLAG0 pin config-
ured as IRQ0
.
11 P0I
(DAI1I)
Programmable Interrupt 0 (DAI High Priority Interrupt). Indicates
if a DAI1I interrupt is latched and is pending (if set, = 1), or no
DAI1I interrupt is pending (if cleared, = 0). This is the higher prior-
ity option.
12 P1I
(SPIAI)
Programmable Interrupt 1 (SPI Transmit or Receive High Priority
Interrupt). Indicates if an interrupt in the primary SPIAI is latched
and is pending (if set, = 1), or no interrupt is pending (if cleared, =
0). This is the higher priority option.
13 P2I
(GPTMR0I)
Programmable Interrupt 2 (General-Purpose IOP Timer 0 Inter-
rupt). Indicates if a GPTMR0I is latched and is pending (if set, = 1),
or no GPTMR0I is pending (if cleared, = 0).
14 P3I (SP1I) Programmable Interrupt 3 (SPORT 1 Interrupt). Indicates if an
SP1I interrupt is latched and is pending (if set, = 1), or no SP1I is
pending (if cleared, = 0). An SP1I interrupt occurs two cycles after
the last bit of an input/output serial word is latched into/from
RXSP1A/TXSP1A, RXSP1B/TXSP1B.
15 P4I (SP3I) Programmable Interrupt 4 (SPORT 3 Interrupt). Indicates if an
SP3I interrupt is latched and is pending (if set, = 1), or no SP3I is
pending (if cleared, = 0). An SP3I interrupt occurs two cycles after
the last bit of an input/output serial word is latched into/from
RXSP3A/TXSP3A, RXSP3B/TXSP3B.
16 P5I (SP5I) Programmable Interrupt 5 (SPORT 5 Interrupt). Indicates if an
SP5I interrupt is latched and is pending (if set, = 1), or no SP5I is
pending (if cleared, = 0). An SP5I interrupt occurs two cycles after
the last bit of an input/output serial word is latched into/from
RXSP5A/TXSP5A, RXSP5B/TXSP5B.
