IP2312 Lithium Battery Charging Module - 0805 Package, a Must-Have for Those with Clumsy Hands

Overview

The IP2312 lithium battery charging IC supports 4.20V/4.30V/4.35V/4.4V lithium batteries, with a maximum current of 3A
for easy hand soldering. All capacitors and resistors are in 0805 packages. Compared to the traditional TP4056, it offers higher current and lower heat generation. The charging

cutoff voltage and constant current charging current are adjusted via the RISET and RVSET pads.
The charging cutoff voltage is adjusted as follows:
4.2V 43K 1% 4.3V 75K 1% 4.35V 100K 1% 4.4V.
The constant current adjustment is: I=135000/Ri (Ri∈45KΩ-170KΩ)
135K-1A
91K-1.5A
NC-2.1A
45K-3A

I hope to implement the button selection initialization mode at the beginning of the program, but it doesn't work...
There are three initialization functions. I hope to select one by pressing a button and then do subsequent tests. However, I find that the button seems to be always skipped and the subsequent program
How to use the PCIE core reference design testbench
The PCIe IP core generated by ISE contains the reference design provided by Xilinx, and a simulation folder with test code. I would like to ask if anyone has used simulation before. I am a little conf
