Functional description
Remark: Please refer to the P89LPC952/954
User’s 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 dened.
Accesses to any dened 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 specied, 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.
