3 LP5569 Programming

3.1 Programming Flow Chart

Figure 40 shows the typical programming flow of the LP5569 device. The program is first typed in with the

Source Edit tab of the EVM software or with the PSPad (or equivalent) text editor (See AN-2227 LP5523

Evaluation Kit regarding PSPad usage.) Then the program is compiled into hex and binary files. Finally,

the hex file is loaded into the LP5569 memory and tested.

3.4 Directives

The directives are not translated directly in the LP5569 device. Instead, directives are instructions for the LASM.exe assembler. Directives are used to adjust the location of the engine 1, 2, and 3 programs in memory and reserve memory resources in the LP5569 SRAM. For example, .segment program1 is a directive which tells the assembler that whatever follows is the program for the program execution engine 1. An overview of the directives is given in the following table.

.segment Adjust the location of the programs in

3.5 Labels

A label is a symbolic address. Labels are used to mark program line(s), like in a branch instruction or when labeling rows in amapping table. Labels must have the colon (:) suffix.

INSTRUCTION

ramp time, PWM

Time is a positive constant (0.000484 × PWM); PWM is a positive or negative constant (–255 to 255). Note: time is rounded by the assembler if needed.

ramp var1, prescale, var2

Var1 is a variable (ra, rb, rc, rd); Prescale is a boolean constant (pre=0 or pre=1); Var2 is a variable (ra, rb, rc, rd).

set_pwm PWM

PWM is a constant (0–255 or 0–FFh).
