Register name: config35 – Address: 0x23, Default: 0xFFFF
Register

Address Bit Name Function
Value
Name
config35 0x23 15:0 sleep_cntl(15:0) Controls the routing of the CMOS SLEEP signal (pin B40) to different blocks. When a 0xFFFF
bit in this register is set, the SLEEP signal will be sent to the corresponding block. The
block will only be disabled when the SLEEP is logic HIGH and the correspond bit is set
to “1”.
These bits do not override SIF bits in config26 that control the same sleep function.

config37 0x25 15:0 iotest_pattern0 Dataword0 in the IO test pattern. It is used with the seven other words to test the input data. 0x7A7A
At the start of the IO test pattern, this word should be aligned with rising edge of FRAME or
SYNC signal to indicate sample 0.
