Special function registers

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

when read (even if it was written with ‘0’). It is a reserved bit and may be used in

future derivatives.

– ‘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.
