gated by the power-down mode logic.
Figure 7. Power-Down Mode Logic
triggering, wake-up, and effects
The power-down modes and their wake-up methods are programmed by setting the PWRD field (bits 15
10)
of the control status register (CSR). The PWRD field of the CSR is shown in Figure 8 and described in Table 20.
When writing to the CSR, all bits of the PWRD field should be set at the same time. Logic 0 should be used when
“writing” to the reserved bit (bit 15) of the PWRD field. The CSR is discussed in detail in the
TMS320C6000 CPU
and Instruction Set Reference Guide
(literature number SPRU189).
