Absolute address
(3)
Only values 1 through 9 are valid, any other value results in no LED driver selected.
Bit[9] is to enable master fader control by the engine. If this bit is set to 1 in engine 1, then master fader 1 is
enabled.

8.5.2.5.1
LOAD_START and LOAD_END
The load_start and load_end instructions define the mapping table locations in SRAM.
NAME
VALUE (d)
DESCRIPTION
SRAM address
0–127
Mapping table start or end address restricted to lower half of memory.
8.5.2.5.2
MAP_START
The map_start instruction defines the mapping table start address in the memory, and the first row of the table is
activated (mapped) at the same time.
NAME
VALUE (d)
DESCRIPTION
SRAM address
0–127
Mapping table start address restricted to lower half of memory.
8.5.2.5.3
MAP_SEL
With the map_sel instruction one, and only one, LED driver can be connected to a program execution engine.
Connecting multiple LEDs to one engine is done with the mapping table. After the mapping has been released
from an LED, the PWM register value still controls the LED brightness.
NAME
VALUE (d)
DESCRIPTION
LED select
0–127
0 = no drivers selected
1 = LED1 selected
2 = LED1 selected
...
9 = LED9 selected
10–127 = no drivers selected
