Trying to make sense of SAMD I2C datasheets
They have two formulas (see SAMD10 datasheet, for example): fSCL = 1 / tLOW + tHIGH + tRISE fSCL = fGCLK / (2 * (5 + BAUD) + fGCLK * tRISE) Am I the only one who thinks that the...

Pin mapping of all USART0 can optionally be moved to high nibble of port
How? On ATxmega64A3U, for example. Not that I need to, just curious.

CLK_CPU and CLK_PER on 0-series
Are they always the same or not? It looks that they are. But I don't see this clearly spelled in the (ATmega4809) datasheet. Interestingly, one of the older ATtiny417/814/816/817...

Serial Downloading
AVR datasheets include Serial Downloading section that define a way to reprogram flash/EEPROM/fuses. Is there something similar for SAMD's?

atprogram without -chiperase
Has anyone tried atprogram without chiperase? Supposedly it should erase the affected pages automatically ("SAM devices will always do this"), but it looks that it does not....

Reading ADC->INTFLAG.reg seems to clear the RESRDY bit. On samd20 and samd21. What am I missing?

SAMD flash write
OK, I understand that it has to be erased in (256 byte) rows. But it looks that it has to be written in 64-byte chunks? Really? Am I missing something? Looking at application...
