7.3 Extended functions
H0U has built-in analog expansion cards 6AT, which can be set and displayed through special
registers. Users only need to set and read the corresponding special registers, no instructions
are required.
D8400～D8409 are display areas, D8410～D8419 are basic parameter setting areas, D8420～
D8429 are AD special parameter setting areas, and D8430～D8439 are DA special parameter
setting areas.
See the table below for the meaning of specific parameters.
