Memory Interface Pins
The ADSP-21mod970 modem pool can be used in one of two modes, Master Mode or Slave Mode. In
Master Mode, Modem Processor 1 operates with full memory (BDMA operation with full external
overlay memory and I/O capability). In Slave Mode, Modem Processor 1 operates in host configuration
(IDMA operation with limited external addressing capabilities). The operating mode is determined by
the state of the Mode C pin during RESET and cannot be changed while the modem pool is running. See
the “Memory Architecture” section for more information.
Full Memory Pins (Mode C = 0) Modem Processor 1 Only
Host Pins (Mode C = 1) Modem Processor 1 and Modem Processors 2-6
In Host Mode, external peripheral addresses can be decoded using the A0, CMS, PMS, DMS, and IOMS signals of Modem Processor 1.
Interrupts
The interrupt controller allows each modem processor in the modem pool to respond individually to
eleven possible interrupts and reset with minimum overhead. The ADSP-21mod970 provides four
dedicated external interrupt input pins, IRQ2, IRQL1, IRQL0, and IRQE (shared with the PF7:4 pins)
for each modem processor. The ADSP-21mod970 also supports internal interrupts from the timer, the
byte DMA port, the serial port, software, and the power-down control circuit. The interrupt levels are
internally prioritized and individually maskable (except power down and reset). The IRQ2, IRQ1, and
IRQ0 input pins can be programmed to be either level- or edge-sensitive. IRQL0 and IRQL1 are level-
sensitive and IRQE is edge sensitive. The priorities and vector addresses of all interrupts are shown in
Table I.
