LP5569: LP5569EVM: Programs not running correctly

Hello,

We're using the LP5569EVM in conjunction with a i.MX8MQ evaluation board to
develop a driver for the LP5569, but we're having some issues.

Below you can find the sequence of I2C reads/writes we use to initialize the
LP5569, load a trivial program (also below) into the SRAM, and start the first
engine.

------------------ 8< ------------------

 001            .segment program1
 002            .segment program2
 003            .segment program3
 004 00 9D01        map_sel 1
 005 01 4064        set_pwm 100
 006 02 C000        end

================================
Labels:

Segments:
program1 = 00
program2 = 00
program3 = 00

================================
Free memory: 252
Errors: 0

------------------ 8< ------------------

The "map_sel 1" command seems to run, since the ENGINE1_MAPPING2 register has a
value of 0x01 after running the sequence below, but the PWM value is never
changed (LED0_PWM is still zero).

Manually changing LED0_PWM works, and the corresponding LED lights up.
