Nuvoton ISD15D00 Troubleshooting Manual page 12

4 VPE + User's board
4.1 Check cloc：reference 3.2
4.2 Check CFG：reference 3.1
4.3 Burn device：reference 3.4
5 User's MCU board + Demo board
5.1 Check SPI commands sequence
① POI：Power on user's board. POI will be executed automatically after reset signal：a high pulse
(>50ms) on RESET pin.
② PU：Before execute commands, send Power Up(0x10) command first.
③ PLAY VP or VM：After PU, it is available to execute PLAY VP or VM commands.
(Example1：PLAY VP：A6000C
EXE VM：B00003 )
5.2 Check SPI waveform：reference 3.6
5.3 Burn device：reference 3.4
5.4 Check Clock： To read CLK CFG：send 0xB600.
5.5 Check CFG：①To read CFG00~CFG09：send 0xBA0000000000000000000000.
First 00 is address for CFG00, next twenty 0 is clock for MISO.
②To read register after CFG10： for example CFG17, send 0xBA1700.
00 is clock for MISO.
※About read back from MISO by waveform, reference 3.6.
5.6 Check Status Byte：send 0x40 and reference 3.7
00 is clock for MISO.
