SAM D21/DA1 Family

48.12 Rev. L – 09/2016


Configuration Summary	Added information on number of pins for the WLCSP pakcage. SAM D21E is offered in 32 pin packages, while the WLCSP has 35 pins.
DSU - Device Service Unit	Testing of On-Board Memories MBIST: Updated description.
Clock System	Disabling a Peripheral: New section added.
SYSCTRL – System Controller	XOSC.AMPGC bit description updated.
EIC – External Interrupt Controller	Interrupts: Added note explaining how it works when the same external interrupt (EXTINT) is common on sevral pins.
EVSYS – Event System	CTRL.SWRST: Added recommendation when doing a software reset.
SERCOM I²C – Inter-Integrated Circuit	Corrected cross references in the Master CTRLA.SCLSM and Slave CTRLASCLSM bits.
TCC – Timer/Counter for Control Applications	Value 0 in CAPTMIN mode is captured only in down-counting mode.
ADC – Analog-to-Digital Converter	Differential and Single-Ended Conversions: Corrected register reference from INPUTCTRL.DIFFMODE to CTRLB.DIFFMODE. RESULT: Corrected description. Reference to "single-ended mode" corrected to "single conversion mode".
Electrical Characteristics at 85℃	Absolute Maximum Ratings: Add ESD warnings. I²S Timing: f_{M_SCKO} and f_{M_SCKI} values for VDD=1.8V moved from the minimum to maximum column. XOSC32K Crystal Oscillator Characteristics: Removed conditions from the parasitic capacitor loads C_XIN32 and C_XOUT32. The difference between package types is so small that it can be ingored.
Schematic Checklist	External Real Time Oscillator: Added note on how to minimize jitter.
Electrical Characteristics at 125°C	Maximum Clock Frequencies: Corrected heading of Table 39-6 say "Device Variant B".
