SPRS292A − OCTOBER 2005 − REVISED NOVEMBER 2005

CPU CSR register description

The CPU control status register (CSR) contains the CPU ID and CPU Revision ID (bits 16−31) as well as the status of the device power-down modes [PWRD field (bits 15−10)], program and data cache control modes, the endian bit (EN, bit 8) and the global interrupt enable (GIE, bit 0) and previous GIE (PGIE, bit 1). Figure 6 and Table 18 identify the bit fields in the CPU CSR register.

For more detailed information on the bit fields in the CPU CSR register, see the TMS320C6000 DSP Peripherals Overview Reference Guide (literature number SPRU190) and the TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189).
