Memory
The IC80C52/32 has separate address spaces for program
and data memory. The program and data memory can be
up to 64K bytes long. The lower 8K program memory can
reside on-chip.(IC80C52 only) Figure 5 shows a map of the
IC80C52/32 program and data memory.
The IC80C52/32 has 256 bytes of on-chip RAM, plus
numbers of special function registers. The lower 128 bytes
can be accessed either by direct addressing or by indirect
addressing. Figure 6 shows internal data memory
organization and SFR Memory Map.
The lower 128 bytes of RAM can be divided into three
segments as listed below and shown in Figure 7.
1.
Register Banks 0-3:
locations 00H through 1FH (32
bytes). The device after reset defaults to register bank
0. To use the other register banks, the user must select
them in software. Each register bank contains eight
1-byte registers R0-R7. Reset initializes the stack
point to location 07H, and is incremented once to start
from 08H, which is the first register of the second
register bank.
2.
Bit Addressable Area:
16 bytes have been assigned
for this segment 20H-2FH. Each one of the 128 bits of
this segment can be directly addressed (0-7FH). Each
of the 16 bytes in this segment can also be addressed
as a byte.
3.
Scratch Pad Area:
30H-7FH are available to the user
as data RAM. However, if the data pointer has been
initialized to this area, enough bytes should be left
aside to prevent SP data destruction.
FFFFH:
64K
1FFFH:
