Description
0: 20 to 65 MHz SSCG Operation
1: 10 to 20 MHz SSCG Operation
0: Normal CLKOUT Slew Rate
1: Increased CLKOUT Slew Rate
0: Normal DATA Slew Rate
1: Increased DATA Slew Rate
0: Data strobed on Falling edge of CLKOUT
1: Data strobed on Rising edge of CLKOUT
00: Normal Mode, Control Signal Filter Disabled
01: Normal Mode, Control Signal Filter Enabled
10: Reserved
11: Reserved
Note – not the same function as PowerDown (PDB)
0: Normal Mode
1: Sleep Mode – Register settings retained.
0: Configurations set from control pins / STRAP pins
1: Configurations set from registers (except I2C_ID)
0: Address from ID[X] Pin
1: Address from Register
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.
0: Set outputs state LOW (except LOCK)
1: Release output LOW state, outputs toggling
normally
Note: This register only workds during LOCK = 1
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
Reserved
0: Strap will determine whether OP_LOW feature is
ON or OFF
1: Turns OFF OP_LOW feature
000: disable
001: 50 MHz ±40%
010: 25 MHz ±40%
011: 16.7 MHz ±40%
100: 12.5 MHz ±40%
101: 10 MHz ±40%
110: 8.3 MHz ±40%
111: 6.3 MHz ±40%
