Remark: Special Function Registers (SFRs) accesses are restricted in the following
ways:
•
•
•
User must not attempt to access any SFR locations not defined.
Accesses to any defined SFR locations must be strictly for the functions for the
SFRs.
SFR bits labeled ‘-’, ‘0’ or ‘1’ can only be written and read as follows:
– ‘-’ Unless otherwise specified, must be written with ‘0’, but can return any value
– ‘0’ must be written with ‘0’, and will return a ‘0’ when read.
– ‘1’ must be written with ‘1’, and will return a ‘1’ when read.
X2 CLKOUT
when read (even if it was written with ‘0’). It is a reserved bit and may be used in
future derivatives.
