PRELIMINARY
Notice: This s not a final specification.
Some parametric imits are subject to change.
FLD automatic display RAM
The FLD automatic display RAM uses the 160 bytes of addresses
0F60
16
to 0FFF
16
. For FLD, the 3 modes of 16-timing ordinary mode,
16-timinggradation display mode and 32-timing mode are available
depending on the number of timings and the presence/absence of
gradation display.
The automatic display RAM in each mode is as follows:
(1) 16-timingOrdinary Mode
The 80 bytes of addresses 0FB0
16
to 0FFF
16
are used as a FLD
display data store area. Because addresses 0F60
16
to 0FAF
16
are not used as the automatic display RAM, they can be the ordi-
nary RAM or serial I/O automatic reverse RAM.
(2) 16-timingGradation Display Mode
The 160 bytes of addresses 0F60
16
to 0FFF
16
are used. The 80
bytes of addresses 0FB0
16
16
are used as an FLD dis-
play data store area, while the 80 bytes of addresses 0F60
16
to
0FAF
16
are used as a gradation display control data store area.
(3) 32-timing Mode
The 160 bytes of addresses 0F60
16
to 0FFF
16
are used as an
FLD display data store area.
[FLD Data Pointer and FLD Data Pointer Reload Register]
FLDDP (0EF8
16
)
Both the FLD data pointer and FLD data pointer reload register are
8-bit registers assigned at address 0EF8
16
. When writing data to this
address, the data is written to the FLD data pointer reload register;
when reading data from this address, the value in the FLD data pointer
is read.
