I have a EVAL-9213 board to do some test. Some test modes in 9213 were not worked very well.
For exmple, i want send user data from register 0x558 to 0x55f, but 9213 can't work.
Some registers configurations were as below:
0x0000 --> 0x81 // soft reset
0x504 --> 0x94 // force ILAS/user data, 8b/10b bypass
0x505 --> 0x1E // 10b data at 8b/10b output, continuous/repeat user test
0x558 to 0x55F --> 0x0F
After these registers enabled, the final datas were not the wanted data.
