ADSP-219x DSP Core Registers Program Sequencer Registers The DSP’s Program Sequencer registers hold page addresses, stack addresses, and other information for determining program execution. Refer to “System Interrupt Controller Registers” on page B-21 for additional information. Table A-6. Program Sequencer Registers Register Initialization After Reset “Interrupt Mask (IMASK) Register and Interrupt Latch (IRPTL) Register” on page A-15 0x0000 “Interrupt Control (ICNTL) Register” on page A-15 0x0000 “Indirect Jump Page (IJPG) Register” on page A-17 0x00 “PC Stack Page (STACKP) Register and PC Stack Address (STACKA) Register” on page A-17 Undefined “Loop Stack Page (LPSTACKP) Register and Loop Stack Address (LPSTACKA) Register” on page A-17 Undefined “Counter (CNTR) Register” on page A-18 Undefined “Condition Code (CCODE) Register” on page A-18 Undefined “Cache Control (CACTL) Register” on page A-19 b#101n nnnn Interrupt Mask (IMASK) Register and Interrupt Latch (IRPTL) Register Figure A-4 on page A-16 shows the bits for these are a non-memory mapped, register group 1 registers (REG1). Interrupt Control (ICNTL) Register Figure A-5 on page A-16 shows this is a non-memory mapped, register group 1 register (REG1). The reset value for this register is 0x0000.
