Hi,
I have a strange behavior and can’t explain.
The ATmega328P supports two external interrupts which are individually enabled
by setting bits INT1 and INT0 in the External Interrupt Mask Register (EIMSK)
The address is $1d. When I look to the documentation te bits 0 and 1 are R/W
and the other

It's the current clock the controller is running at.
It's a double cell number, since the 16bit controllers
run too fast to keep this number in a single cell.
