2019年2月13日 · The SAMD21 has a separate real time clock (RTC), powered by an on board 32.78 crystal, that runs at a full 48 MHz. Also, almost every pin is tied to timer-counter, giving you a lot more PWM-capable I/O pins so you'll have plenty …
The SAMD21 & SAMDR21 have 2 groups of 32 bit port controllers for configuring GPIO direction and output values. In addition, you can directly set the direction pins in the DIR register and output levels via the OUT register. Per the SAMD21 Datasheet states: The IO Pin Controller (PORT) controls the I/O pins of the device.
