Description
The protection bit in the internal flash is set. SAB access is restricted. This bit
will read as one during reset.
The SAB bus is busy with a previous transfer. This could indicate that the CPU
is running on a very slow clock, the CPU clock has stopped for some reason
or that the part is in constant reset.
The Chip erase operation has not finished.
This bit will be set if the CPU is halted. This bit will read as zero during reset.
This bit will be set if AW has reset the CPU using the RESET command.
