Host Interface DSP Core Interrupts
The HI08 can request interrupt service from either the DSP56309 or the host processor.
The DSP56309 interrupts are internal and do not require the use of an external interrupt
signal. When the appropriate interrupt enable bit in the HCR is set, an interrupt
condition caused by the host processor sets the appropriate bit in the HSR, generating an
interrupt request to the DSP56309. (See
interrupts caused by the host processor by jumping to the appropriate interrupt service
routine. There are three possible interrupts:
¥ Host command
¥ Transmit data register empty
¥ Receive data register full
Although there is a set of vectors reserved for host command use, the host command can
access any interrupt vector in the interrupt vector table. The DSP interrupt service
