Boot port size. Reflects the default selection for the boot port size if the boot device is
configured to be external.
00 Internal (32 bits) (This is the value used for this device.)
01 16 bits
10 8 bits
11 32 bits
The default function of the boot port size can be overridden during reset configuration.
Boot select. Reflects the default selection for the boot device.
0 Boot from internal boot device (This is the value used for this device.)
1 Boot from external boot device
Reserved, should be cleared.
Chip configuration mode. Reflects the default chip configuration mode.
0 Single-chip mode (This is the value used for this device.)
1 Master mode
The default mode can be overridden during reset configuration. If the default is overridden,
the CCR[MODE0] reflects the mode configuration.
