2.1.1.3 Special Function Registers
The 8032 provides a distinct memory area for accessing Special
Function Registers (SFRs). SFRs are used in the program to control
timers, counters, serial I/Os, port I/Os, and peripherals. SFRs reside from
address 0x80 to 0xFF, and can be accessed by bits, bytes, and words.
The special function registers are listed in
Table 2.2
.
2.1.2 Archimedes Compiler Features
The user should be familiar with several Archimedes compiler features
that are related to the above 8032 features before reading the source
code.
2.1.2.1 Control Directives
The four control directives are: AREGS/NOAREGS, REGISTERBANK,
and SMALL.
