7. Functional description

Remark: Please refer to the P89LPC9351 User manual for a more detailed functional

description.

7.1 Special function registers

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 ‘-’, ‘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.
