(1) Not applicable for devices with HF crystal oscillator only.
(2) Characterized with a SSP-T7-FL (SMD) crystal with a load capacitance of 3.7 pF. The internal and external load capacitance are chosen to closely match the required 3.7-pF load.
(3) Characterized with a Micro Crystal MS1V-T1K crystal with a load capacitance of 12.5 pF. The internal and external load capacitance are chosen to closely match the required 12.5-pF load.
(4) Low-power mode 3.5, 12-pF crystal, includes SVS test conditions:
Current for RTC clocked by XT1 is included. Current for brownout and SVS are included (SVSHE = 1). Core regulator is disabled.
