Subsequently, pressing the POWER button will initiate the same power upsequence as shown in Table 5-1.The various power rails supplied by the PMIC are discussed in the SMD Power Rails subsection. Other featuresof the Dialog PMIC implemented by the MCIMX53SMD board are discussed in the Backlight LED Driver, Touch-Screen Operation, and Miscellaneous sub-sections.5.2.1.
