8.13.6 MUX_MAP_NEXT

This instruction sets the next row active in the mapping table each time it is called. For example, if the 1st row is active

at this moment, after mux_map_next instruction call the 2rd row will be active like in the block diagram shown in

Figure 32 below.

Figure 32. MUX_MAP_NEXT Command

If the mapping table end address is reached, activation will roll to the mapping table start address next time when the

mux_map_next instruction is called. Engine will not push a new PWM value to the LED driver output before set_pwm

or ramp instruction is executed. If the mapping has been released from an LED, the value in the PWM register will still

control the LED brightness. If the mapping is released from the GPO pin, serial bus control takes over the GPO state.

COMPILER COMMAND SYNTAX: MMN;

This command doesn’t support any parameters.

8.13.7 MUX_MAP_PREV

This instruction sets the previous row active in the mapping table each time it is called. For example, if the 3rd row is

active at this moment, after mux_map_prev instruction call the 2nd row will be active like in block diagram shown in

Figure 33 below.
