Figure A-38 RCIM II PCI Interrupt Routing Registers (PARR, PBRR, PCRR, PDRR)
Setting a bit in a PCI interrupt routing register routes selected interrupts to the designated PCI interrupt. The
default power-up value is everything routed to PCI A. Setting bits in multiple registers will drive multiple
PCI interrupt lines.
Offsets: PARR1: 00A0, PARR2: 00A4, PBRR1: 00B0, PBRR2: B4, PCRR1: 00C0, PCRR2: 00C4,
PDRR1: 00D0, PDRR2 00D4
Figure A-39 RCIM II DDS Adjust Register (DDS)
Writing to the Direct Digital Synthesizer Adjust register loads the 32-bit frequency control word into the
onboard AD9851 DDS.
