BOOTSEL — Boot Select Bit
MODE — Chip Configuration Mode Bit
The Chip Identification Register (CIR) is a read-only register; writing to
CIR has no effect.
This read-only bit reflects the default selection for the boot device.
The default function of the boot select can be overridden during reset
configuration. If the default mode is overridden, the CSEN bit in
CSCR0 bit reflects the boot device configuration.
The read-only MODE bit reflects the chip configuration mode.
The default mode can be overridden during reset configuration. If the
default mode is overridden, the MODE bits in CCR reflect the mode
configuration.
