#### Programmer self-testing method
**The following tests basically cover the functionality that all RT809H applications need to use**：
K switching state
VPP protection circuit
Overcurrent protection test
20MHz high frequency data reading and writing
Pull-up and pull-down open&short circuit to test
Open and short circuit test of HMI interface and VGA ISP interface
48 Channel VCC/VPP/GND driver open and short circuit test
48-channel IO contact resistance(from the outside of the current limiting resistor of the IO to the locking seat, total resistance value is not exceeding 10ohs)
**Pay attention**：
Please connect the programmer USB cable to the computer USB2.0 port(there are only four contacts inside the port)【the blue one is the 3.0 port(there are 9 contacts in this port】;
If you use a desktop host, please insert the USB cable into the mainboard native USB interface(typically post);
Only keep the USB cable connect to the computer;
Find the RT809H icon on your desktop and double click it to open;
The software interface is as follows, the normal connection with serial number showing;
Input “SELF”at the chip print box;
Under Model, double-click “SELFTEST”;
Information box prompt “Algorithm updated OK”;
#### Reading
Click “Read”on the left;
The information box indicates “SelfTest 0 test pass”
The end of the self-test, the programmer is basically normal;
If it's not the “SelfTest 0 test pass”, suspected that the faults need to be checked.
There are two ways to prepare a self-test board and a short wiring:
Two self-test boards can be made or purchased;
Self-test board 1.has no components, only have pins;
Self-test board 2 has 24 patch resistors and pins 0603;
The VGA test header needs to be prepared with an additional VGA header, short spliced 4-11 and 12-15 pin.
#### Write
Insert the self-test board 1, and VGA test head plug into the VGA ISP interface, click the “write”and it shows “self-test 1 pass”.
#### Verify
Plug in the self-test board 2,click”Verify” and it shows “self-test 2 pass”
