"No need for an external oscillator" ATMEGA4809
I'm sure this has been discussed many times, but I just cannot find a clear answer. The USART section of the ATMEGA4809 datasheet says "No need for an external oscillator". Any...

Has anyone used the buffered mode on SAME54/SAMD51? It doesn't seem to work as expected. Or perhaps I don't understand how it is expected to work. I expect it not to write...

SmartEEPROM and number of SEEP
This is on SAMD51/SAME54. Trying to make sense of datasheets. How do they come up with the numbers of SEEP? Some of that doesn't quite make sense. Especially, for example, the "...

EVSYS_ID_USER_ADC_START on SAML21 doesn't seem to work unless I select EVSYS_CHANNEL_PATH_ASYNCHRONOUS. On SAMD21 EVSYS_ID_USER_ADC_START is "Asynchronous path only". But on...

Trying to make sense of SAML21 datasheet
It says "When an analog peripheral is enabled, the analog output of the peripheral will interfere with the alternative functions of this pin. This is also true even when the...

The comparator output generates an event tied to a TC timer capture. Everything seems good if AC_COMPCTRL_INTSEL_RISING. I see both TC->COUNT16.INTFLAG.reg and AC->INTFLAG....

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.

avr-gcc bug?
The toolchain is "AVR 8-bit Toolchain v3.62 – Windows", which I just got from: https://www.microchip.com/mymicr...   #include <stdio.h> volatile uint8_t vv; static...

Standalone atprogram (again)
I have been using a standalone atprogram for a while. It's from a 6.2 Studio and the USB drivers:   from http://ww1.microchip.com/downloa...   from https://www.microchip...

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?
