UDEF1
User defined information status 1 for debug purpose
Bit [15:8]
UDEF2
User defined information status 2 for debug purpose
Bit [23:16] UDEF3
User defined information status 3 for debug purpose
Bit [25:24] HT
Holding time for LED signal (Default=00)
00=8msec
01=16msec
10=32msec
11=64msec
Bit [27:26] LCLK
LED Clock frequency (Default=00)
00= 100M/8=12.5Mhz
01= 100M/16=6.25Mhz
10= 100M/32=3.125Mhz

Bit [30:28] Reserve
Bit [31]
SS
Start Shift the status bits out from the master device.
This bit has no effect on the slave chip.
Note:
UDEF1-UDEF3 are used for debug purpose. The contents of UDEF1-3 are loaded by CPU and the usage of
these are up to software.
