Event Control
DMA2 Channel 1 Interrupt (SPORT0 Tx) IVG9 The ADSP-BF561 provides the user with a very flexible mecha­ DMA2 Channel 2 Interrupt (SPORT1 Rx) IVG9 nism to control the processing of events. In the CEC, three DMA2 Channel 3 Interrupt (SPORT1 Tx) IVG9 registers are used to coordinate and control events. Each of the registers is 16 bits wide, while each bit represents a particular DMA2 Channel 4 Interrupt (SPI) IVG9 event class. DMA2 Channel 5 Interrupt (UART Rx) IVG9 • CEC Interrupt Latch Register (ILAT) – The ILAT register DMA2 Channel 6 Interrupt (UART Tx) IVG9 indicates when events have been latched. The appropriate DMA2 Channel 7 Interrupt IVG9 bit is set when the processor has latched the event and DMA2 Channel 8 Interrupt IVG9 cleared when the event has been accepted into the system. DMA2 Channel 9 Interrupt IVG9 This register is updated automatically by the controller, but may also be written to clear (cancel) latched events. This DMA2 Channel 10 Interrupt IVG9 register may be read while in supervisor mode and may DMA2 Channel 11 Interrupt IVG9 only be written while in supervisor mode when the corre­ Timer0 Interrupt IVG10 sponding IMASK bit is cleared. Timer1 Interrupt IVG10 • CEC Interrupt Mask Register (IMASK) – The IMASK reg­ Timer2 Interrupt IVG10 ister controls the masking and unmasking of individual Timer3 Interrupt IVG10 events. When a bit is set in the IMASK register, that event is Timer4 Interrupt IVG10 unmasked and will be processed by the CEC when asserted. A cleared bit in the IMASK register masks the event, Timer5 Interrupt IVG10 thereby preventing the processor from servicing the event Timer6 Interrupt IVG10 Rev.
