(1) First Supply detection allows power-up as soon as supply voltage is applied, even if EN/PB/VSENSE pin is at OFF_REQ status. FSD can be used in combination with any ON-request configuration, EN, PB or VSENSE. At first power-up the EN/PB/VSENSE pin is treated as if it had a valid ON request.
(2) The AM62 starter kit comes with the TPS6521904 PMIC by default, supporting VDD_CORE=0.85V. To support VDD_CORE=0.75V, the following changes are required: TPS6521904 PMIC needs to be replaced with TPS6521903, R699 needs to be uninstalled, and R123 needs to be mounted.
(3) See Section 5 for a comparison of the two VDD_CORE operating points.
