3.6 Instruction Set Details
Instructions are executable statements. The LASM assembler translates text-based language source
instructions into hex-based executable codes. This section provides the syntax with detailed examples for
all the LP5569 instructions supported by the LASM assembler.

(HEX)
load_start address
Address is a label which
specifies where to find
the first row.
Defines the start
address of the mapping-
data table. The
mapping-data-table start
address is restricted to
the lower half of
memory. load_start row1 ;
The first row can be
found at the address
marked with row1. 1001 1110 0000 0000
Assumed that row1
points to addr 00h. 9E00
map_start address
Address is a label which
specifies where to find
the first row.
Defines the start
address of the mapping-
data table and sets the
row active. map_start row1 ;
The first row can be
found at the address
marked with row1. 1001 1100 0000 0000 9C00
load_end address
Address is a label which
specifies where to find
the first row.
Defines the last address
of the mapping-data
table. The mapping-
data-table end address
is restricted to the lower
half of memory. load_end row9 ;
The last row can be
found at the address
marked with row9. 1001 1100 1000 1000 9C88
map_sel output
Output is a constant (0
to 9); 10 through 127 =
no drivers selected.
Connects one and only
one LED output to an
engine. map_sel 1 ;
D1 output is connected
to the engine. 1001 1101 0000 0001 9D01
map_clr Clears engine-to-driver
mapping. map_clr 1001 1101 0000 0000 9D00
map_next Sets the next row active
in the mapping table. map_next 1001 1101 1000 0000 9D80
map_prev Sets the previous row
active in the mapping
table. map_prev 1001 1101 1100 0000 9DC0
load_next The index pointer is set
to point to the next row
in the mapping-data
table. load_next 1001 1101 1000 0000 9D81
load_prev The index pointer is set
to point to the previous
row in the mapping-data
table. load_prev 1001 1101 1100 0000 9DC1
load_addr address
Address is a label which
specifies the row to
which the pointer is to
be moved.
Sets the index pointer to
point to the mapping-
data-table row defined
by address. An SRAM
address containing
mapping data is
restricted to lower half of
memory. load_addr row2 1001 1111 0000 0001 9F01
map_addr address
Address is a label which
specifies the row to
which the pointer is to
be moved.
Sets the index pointer to
point to the mapping-
data-table row defined
by address and sets the
row active. An SRAM
address containing
mapping data is
restricted to lower half of
memory. map_addr row2 1001 1111 1000 0001 9F81
