8.1 Special function registers
Remark: Please refer to the P89LPC933/934/935/936 User manual for a more detailed
functional description.
Remark: SFR 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 ‘-’, logic 0 or logic 1 can only be written and read as follows:
– ‘-’ Unless otherwise specified, must be written with logic 0, but can return any
– Logic 0 must be written with logic 0, and will return a logic 0 when read.
– Logic 1 must be written with logic 1, and will return a logic 1 when read.
value when read (even if it was written with logic 0). It is a reserved bit and may be
used in future derivatives.
