Data Sheet U17848EJ3V0DS
3.5 Data Memory (RAM): 32
×
4 Bits
The data memory, which is a static RAM consisting of 32
×
4 bits, is used to retain processed data. The data
memory is sometimes processed in 8-bit units. R0 can be used as the ROM data pointer.
RF is also used as the ASR.
After reset, R0 is cleared to 00H and R1 to RF retain the previous data (undefined when turning on the power).
Figure 3-4. Data Memory Configuration
Notes 1.
R0 alternately functions as the ROM data pointer (refer to
3.6 Data Pointer (DP)
).
2.
RF alternately functions as the PC address stack (refer to
3.3 Address Stack Register (ASR (RF)
).
