Figure 8-2. Relationships between Register File and Data Memory
8.2 Function of Register File
8.2.1 Function of register file
The register file is a collection of registers that set the conditions of the peripheral hardware by using the PEEK
or POKE instruction.
The registers that control the peripheral hardware are allocated to addresses 00H-3FH. These registers are
called control registers.
Addresses 40H-7FH of the register file overlap the ordinary data memory. These addresses can therefore
be read or written by not only the MOV instruction but also the PEEK and POKE instructions.
8.2.2 Functions of control registers
The control registers are used to set the conditions of the peripheral hardware listed below.
For the details of the peripheral hardware and control registers, refer to the description of each peripheral
hardware.
Port
8-bit timers/counters (TM0, TM1)
Basic interval timer (BTM)
A/D converter
Serial interface (SIO)
Interrupt function
Stack pointer (SP)
