10: Reserved
11: Reserved
1 R/W 0 SLEEP
Note – not the same function as PowerDown (PDB)
0: Normal Mode
1: Sleep Mode – Register settings retained.
0 R/W 0 REG Control 0: Configurations set from control pins / STRAP pins
1: Configurations set from registers (except I2C_ID)
1 1 Slave ID
7 R/W 0
0: Address from ID[X] Pin
1: Address from Register
6:0 R/W 1110 ID[X]
000
Serial Bus Device ID, Four IDs are:
7b '1110 001 (h'71)
7b '1110 010 (h'72)
7b '1110 011 (h'73)
7b '1110 110 (h'76)
All other addresses are Reserved.
2 2 Des Features 1 7 R/W 0 OP_LOW
0: Set outputs state LOW (except LOCK)
1: Release output LOW state, outputs toggling
normally
Note: This register only workds during LOCK = 1
6 R/W 0 OSS_SEL
Output Sleep State Select
0: CLKOUT, DO[23:0], CO1, CO2, CO3 = Tri-State,
LOCK = Normal, PASS = H
1: CLKOUT, DO[23:0], CO1, CO2, CO3 = L, LOCK =
Normal, PASS = H
