3.2.3
Boot Complete (BOOTCMPLT) register
The BOOTCMPLT register contains a BC (boot complete) field in bit 0, and a ERR (boot error) field in bits
19:16.
The BC field is written by the external host to indicates that it has completed boot. In the bootloader code,
the CPU can poll for this bit. Once this bit = 1, the CPU can begin executing from DSPBOOTADDR.
The ERR field is written by the bootloader software if the software detects a boot error. Coming out of a
boot, application software can read this field to determine if boot was accomplished. Actual error code is
determined by software.
