MULTI-BYTE I2C COMMAND SEQUENCE
To correctly function with the Monahan’s Power Management
I2C 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 followed by the
Device address, which is sent only once, followed by the 8 Bit
register address, then 8 bits of data. The I2C 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 I2C device address
for each transaction. A, M, X, and Z are Random numbers.

INCREMENTAL REGISTER I2C 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 (de-
fault) to random address or address incrimination will be used.
