10.4.1 Normal Startup
During a normal reset cycle (e.g. after the battery or a charger is inserted; (see Reset generator and XON-Key on page
118) ), after V2_5 is above V POR and Vsupply is above VRESET RISE a normal startup happens:
The external capacitor on CREF is charged to 1.8V
The 3bit A/D conversion is performed to measure the external resistor value RPROGRAM
Startup State machine reads out the internal Boot-ROM (address defined by boot_ctrl ), Start sequence of Step-
Down Converter and LDO’s controlled by the Boot-ROM
Reset-Timer is set by the Boot-ROM
The reset is released when the Reset Timer expires (external pin XRESET)
