Atmel 8051 Microcontrollers Hardware Manual 2-68
4316E–8051–01/07
2.2 Special Function
Registers
A map of the on-chip memory area called SFR (Special Function Register) space is
shown in Figure 2-1. SFRs marked by parentheses are resident in the microcontroller
which have the Timer2 feature.Note that not all of the addresses are occupied. Read
accesses to these addresses will in general return random data.
Note: Reserved
User software should not write to the reserved locations, since they may be used in
derivative Atmel 8051 products to invoke new features. The functions of the SFRs are
described as below.
2.2.1 Accumulator ACC is the Accumulator register. The mnemonics for accumulator-specific instructions,
however, refer to the accumulator simply as A.
2.2.2 B Register The B register is used during multiply and divide operations. For other instructions it can
be treated as another scratch pad register.
