IPWR_9			XOSC _48_MHz	VDDIO = AVDD = 3.3V	2	2	mA	48 MHz crystal
IPWR_11			XOSC _48_MHz	VDDREG = 3.3V	7	49	mA	48 MHz crystal
Note: Typical values at 25°C only. Conditions: No peripheral modules are operating (i.e. all peripherals inactive) APB Peripheral bus clocks: default settings after reset CMCC Cache disabled MCU is running on Flash with automatic wait state VREG_USB disabled I/Os are inactive input mode with input trigger disabled All clock generation sources disabled unless otherwise specified WDT, CFD Clock Fail Detect disabled
