28 / 52 page  LP8754 SNVS861A – FEBRUARY 2014 – REVISED AUGUST 2014 www.ti.com Programming (continued) 7.5.1.5 Auto-Increment Feature The auto-increment feature allows writing several consecutive registers within one transmission. Every time an 8- bit word is sent to the LP8754, the internal address index counter will be incremented by one, and the next register will be written. Table 4 below shows writing sequence to two consecutive registers. Note: the auto- increment feature does not work for read. Table 4. Auto-Increment Example Master Start Device Write Register Data Data Stop Action Address Address = 60H LP8754 ACK ACK ACK ACK Action 7.6 Register Maps 7.6.1 Register Descriptions The LP8754 is controlled by a set of registers through the system serial interface port or through the Dynamic Voltage Scaling interface. Table 5 below lists device registers, their addresses and their abbreviations. A more detailed description is given in the sections VSET_B0 to INT_MASK_2. Many registers contain bits, that are reserved for future use. When writing to a register, any reserved bits should not be changed. Table 5.
