Functional description
Remark:
Please refer to the P89LPC932A1 User manual for a more detailed functional
description.
7.1 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 ‘-’, 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
value when read (even if it was written with logic 0). It is a reserved bit and may be
used in future derivatives.
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.
