Data Setup
When data is stored in the FLD automatic display RAM, the
last data of segment PA is stored at address 0F80
16
, the last
data of segment P8 is stored at address 0F90
16
, the last data
of segment P9 is stored at address 0FA0
16
, the last data of
segment P3 is stored at address 0FB0
16
, the last data of seg-
ment P0 is stored at address 0FC0
16
, and the last data of
segment P1 is stored at address 0FD0
16
to allocate in se-
quence from the last data respectively. The first data of the
segment PA, P8, P9, P3, P0, and P1 is stored at an address
which adds the value of (the digit number–1) to the corre-
sponding address 0F80
16
, 0F90
16
, 0FA0
16
, 0FB0
16
, 0FC0
16
,
and 0FD0

.
Set the low-order 4 bits of the FLD data pointer reload register
to the value given by the number of digits–1. “1” is always writ-
ten to bit 6 and bit 4, and “0” is always written to bit 5. Note that
“0” is always read from bits 6, 5 and 4 when reading.
