2.6 Data Pointer (DP): 12 Bits
The ROM data table can be referenced by setting the ROM address in the data pointer to call the ROM contents.
The lower 8 bits of the ROM address are specified by R0 of the data memory; and the higher 4 bits by bits 4
to 7 of the P3 register (CR0).
After reset, the pointer contents become 000H.
Figure 2-5. Data Pointer Configuration
Note Set DP10 and DP11 to 0 in the case of the
PD67 and 67A, and set DP10 to 0 in the case of the PD68
and 68A.
2.7 Accumulator (A): 4 Bits
The accumulator, which refers to a register consisting of 4 bits, plays a leading role in performing various
operations.
After reset, the accumulator contents are left undefined.
