The BCx bit indicates the boot complete status of the corresponding C66x CorePac. All BCx bits are sticky
bits — that is, they can be set only once by the software after device reset and they will be cleared to 0 on
all device resets (warm reset and power-on reset).
Boot ROM code is implemented such that each C66x CorePac sets its corresponding BCx bit immediately
before branching to the predefined location in memory.
9.2.3.11 DSP BOOTADDR NS Registers (DSP_BOOT_ADDR0_NS to DSP_BOOT_ADDR3_NS)
DSP_BOOT_ADDR0_NS through DSP_BOOT_ADDR3_NS registers control the boot address for C66x
CorePac 0 through C66x CorePac 3 in non-secure mode in either secure device or non-secure device
respectively. The DSP_BOOT_ADDRx_NS Register is shown in Figure 9-22 and described in Table 9-38.
