8.3.1 Device Status Register
The Device Status Register depicts the device configuration selected upon a power-on reset by either the POR or RESETFULL pin. Once set, these bits will remain set until the next power-on reset. The Device Status Register is shown in Figure 8-1 and described in Table 8-3.

BOOTMODE[12:0] |
Determines the bootmode configured for the device. For more information on bootmode, see Section 6.27 and see the Bootloader for the C66x DSP User's Guide |
| 0 |
LENDIAN |
Device Endian mode (LENDIAN) — Shows the status of whether the system is operating in Big Endian mode or Little Endian mode.
- 0 = System is operating in Big Endian mode
- 1 = System is operating in Little Endian mode
