PRODUCTION DATA.
The Power State Control register (PWRSTATECTL) is controlled by the software to indicate the power-saving mode. Under ROM code, the C66x CorePac reads this register to differentiate between the various power saving modes. This register is cleared only by POR and is not changed by any other device reset. See Hardware Design Guide for KeyStone II Devices for more information. The PWRSTATECTL register is shown in Figure 10-21 and described in Table 10-40.
