3.2.3
The bit protection scheme prevents direct software writing of selected bits (i.e., protected
bits) using the PASSWD register. When the bit field MODE is 11
B
, writing 10011
B
to the
bit field PASS opens access to writing of all protected bits, and writing 10101
B
to the bit
field PASS closes access to writing of all protected bits. Note that access is opened for
maximum 32 CCLKs if the “close access” password is not written. If “open access”
password is written again before the end of 32 CCLK cycles, there will be a recount of
32 CCLK cycles. The protected bits include the N- and K-Divider bits, NDIV and KDIV;
the Watchdog Timer enable bit, WDTEN; and the power-down and slow-down enable
bits, PD and SD.

These two bits cannot be written directly. To change

, the bit field PASS
must be written with 11000

MODE[1:0] be registered.
