10.3.6 OPTION — System configuration options register 1

System config. options 1
(OPTION)
The special-purpose OPTION register sets internal system configuration
options during initialization. The time protected control bits (IRQE, DLY,
FCME and CR[1:0]) can be written to only once in the first 64 cycles after
a reset and then they become read-only bits. This minimizes the
possibility of any accidental changes to the system configuration. They
may be written at any time in special modes.
