• Manufacturer Part Number: ADM6996L-AA-T-1
• Manufacturer: Lantiq

Specifications of ADM6996L-AA-T-1

• Lead Free Status / RoHS Status: Supplier Unconfirmed

Figure 4
Preamble: At least 32 continuous 1
Start: 01
Opcode: 10
Table select: 1
Register Address: Read Target register address. (7 bits)
TA: Turn Around.
Register Data: 32 bit data.
Counter output bit sequence is bit 31 to bit 0.
If a user reads the EEPROM then 32 bits of data will separate as two EEPROM registers. The sequence is:
1. Register +1, Register (Register is even number)
2. Register, Register-1(Register is Odd number)
Example:
Read Register 00
Read Register 03
Idle: EESK must send at least one clock pulse at idle time
ADM6996L/LX issue Reset internal counter command
EESK: Similar to the MDC signal
EDI: Similar to the MDIO signal
ECS: Must keep low.
