SPECIAL FUNCTION REGISTERS
Note: Special Function Register (SFR) accesses are restricted in the following ways:
1. User must NOT attempt to access any SFR locations not defined.
2. SFR bits labeled ’-’, ’0’ or ’1’ can ONLY be written and read as follows:
- ’-’ 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.
