FUNCTION DESCRIPTION
Operational Registers
R0
(Indirect Addressing Register)
R0 is not a physically implemented register. It is useful as indirect addressing pointer. Any instruction using
R0 as register actually accesses data pointed by the RAM Select Register (R4).
R1
(TCC)
Increased by an external signal edge applied to TCC , or by the instruction cycle clock.
Written and read by the program as any other register.
R2
(Program Counter)
The structure is depicted in Fig. 4.
Generates 8Kx13 on-chip ROM addresses to the relative programming instruction codes.
”JMP” instruction allows the direct loading of the low 10 program counter bits.
“CALL” instruction loads the low 10 bits of the PC, PC+1, and then push into the stack..
“RET’’ (“RETL k”, “RETI”) instruction loads the program counter with the contents at the top of stack.
