Introduced two new IRQs  per vector; one to track pending, and one to
track running state. So you can see any latency issues.
Also introduced a global pending/running IRQ, so you can track issues if
your interrupts overrun etc.

It is reasonably transparent, and seems to have had little impact on the

Avoid buffer overrun on smaller AVRs

On smaller AVRs, such as the attiny13, MAX_IOs will be larger than the

fifo: prevent potential misuse of _get_write_size()

Using the number obtained from _get_write_size() and writing that many
items to the fifo yields to _isempty() becoming true and not to
_isfull() becoming true.

I got caught assuming the latter.

To avoid thinking about edge cases and prevent potential misuse of
_get_write_size(), I suggest that it returns one unit less, thus, a
number between 0 and (fifo_size-1).  E.g., if there is only one place
left in the fifo, i.e., _isfull() is true, it then returns 0, preventing
us to fill that place and get into a wrap overflow situation.

(Michel: Thanks for the great architecture you laid out and the great
code.)

flash: Add support for TEMPPAGE writing.

The proper way to write to flash on the AVR is to write
to the temp page and then write that temp page to flash.
This allows cancellation with the RWWSRE bit for clearing
out the temp page without writing it to flash.

This fixed a bug where the RWWSRE bit was being set in a
command, but the flash driver was improperly writing whatever
was in r0/r1 to the first address in the page, overwriting
what was already there. In reality, the code running on the
core was trying to just flush the temp page or unlock the read
while write section.

Add initial support for the ATmega128RFR2 which according to Atmel is a

I have found this to not be entirely true. All of the changes (new
