5.8 Bit Sequential Buffer ... 16 bit
The bit sequential buffer is a special data memory for
bit control. Since this buffer can easily operate bits by
sequentially changing address and bit specifications, it
can be conveniently be used for bit-wise processing of
data having long bit lengths.

5.9 Power-On Flag (Mask Option)
The power-on flag (PONF) is only set (1) when the
power-on reset circuit is activated and the power-on
reset signal is generated (see Figure 8-1).
PONF is mapped on bit 0 at address FD1H of the data
memory space and is manipulated by a bit manipula-
tion instruction
However, it cannot be set(1) by the SET1 instruction.
