I
2C Compatible Interface (Continued)
MULTI-BYTE I
2C COMMAND SEQUENCE
To correctly function with the Monahan’s Power Manage-
ment I
2C the LP3972’s I2C serial interface shall support
Random register Multi-byte command sequencing: During a
multi-byte write the Master sends the Start command fol-
lowed by the Device address, which is sent only once,
followed by the 8 Bit register address, then 8-bits of data.
The I
2C slave must then accept the next random register
address followed by 8 bits of data and continue this process
until the master sends a valid stop condition.
A Typical Multi-byte random register transfer is outlined
below:
Device Address,
Register A Address, Ach, Register A
Data, Ach Register M Address, Ach,
Register M Data, Ach Register X
Address, Ach, Register X Data, Ach
Register Z Address, Ach, Register Z
Data, Ach, Stop
Note: the PMIC is not required to see the I
2C device address
for each transaction. A, M, X, and Z are Random numbers.

INCREMENTAL REGISTER I
2C COMMAND SEQUENCE
The LP3972 supports address increment (burst mode).
When you have defined register address n data bytes can be
sent and register address is incremented after each data
byte has been sent. Address incrimination may be required
for non XScale applications. User can define whether multi-
byte (default) to random address or address incrimination
will be used.
