EM78P163N
8-Bit Microcontroller with OTP ROM
5.1 Operational Registers
5.1.1 R0 (Indirect Addressing Register)
R0 is not a physically implemented register. It is used as an indirect addressing
pointer. Any instruction using R0 as a pointer actually accesses data pointed by the
RAM Select Register (R4).
5.1.2 R1 (Timer Clock/Counter)
Incremented by an external signal edge, through the TCC pin, or by the instruction
cycle clock.
External signal of TCC trigger pulse width must be greater than one instruction.
The signals to increase the counter are determined by Bit 4 and Bit 5 of the CONT
register.
Writable and readable as any other registers.
5.1.3 R2 (Program Counter) and Stack
Depending on the device type, R2 and hardware stack are 10-bit wide. The
structure is depicted in the following figure.
Figure 5-2 Program Counter Organization
The configuration structure generates 1K×13 bits on-chip OTP ROM addresses to
the relative programming instruction codes. One program page is 1024 words long.
R2 is set as all "0" when under Reset condition.
"JMP" instruction allows direct loading of the lower 10 program counter bits. Thus,
"JMP" allows the PC to go to any location within a page.
