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 17 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).
