If PRL_ON = 0, the testing will be one by one memories group under a controller.

If PRL_ON = 1, all memories under a controller will execute memory self-testing simultaneously.

If user needs to test specific memory, the setting in SDI command as following,
PRL_ON = 1
GRP_EN = assign group number which will be test
MEM_ID = assign MEM_ID under the GRP_EN
