MicroPython • Question about PIO mode

Hardware：Raspberry Pi Pico

Software Development Environment：Micropython

Purpose：Turn on a back light（the back light is producing at present, so now I only have LED driver specification：https://imgur.com/MfJhHsf）

Hello, I am a beginner, learning Micropython with raspberry Pico.

First of all, here is the code that I wrote:

Here is the diagram that tested by a logic analyzer:

And here is the way how I connected Pico with logic analyzer:

GP10 SCK　 →Channel 0

GP12 MOSI →Channel 1

GP11 SCS →Channel 2

GP 17 DISP →Channel 3

GP 19 EXTCOMIN →Channel 4

GP 2 VDD →Channel 5

I'm trying to figure it out now:

How does it send 1 byte at a time, and I want to set it to send 16 bits at a time. How to modify the code?
