Upper 128 Bytes of Internal RAM
The upper 128 bytes (indirect addresses 80H to FFH) of
internal RAM can only be accessed by indirect addressing.
Special Function Registers
Figure 9 gives an overview of the Special Functions Regis-
ter (SFR) space (direct addresses 80H to FFH). The SFR
space contains the accumulator, port latches, timers and
peripheral controls. These registers are accessible only by
direct addressing.
Figure 9.
SFR Memory Map
Notes:
1. These addresses are bit-addressable.
2. The shaded cells indicate those which are accessible on the 8032.
16 addresses in the SFR space are both byte-and bit-
addressable. The bit addressable SFRs are the addresses
ending with 0H or 8H. The bit addresses in this area are
80H through FFH. See Figure 10 for the correspondence
between byte and bit addresses.
