2015-01-26Clear SoftwareSerial rx delay if no interrupt register is foundMatthijs Kooijman
Before enabling interupts, begin would see if the given receive pin actually has an associated PCINT register. If not, the interrupts would not be enabled. Now, the same check is done, but when no register is available, the rx parameters are not loaded at all (which in turn prevents the interrupt from being enabled). This allows all code to use the same "is rx enabled" (which will be added next).
2014-11-25Fix atomicity issues in SPI::beginTransaction and SPI::endTransaction ↵Cristian Maglie
(Andrew Kroll) Previously, it could happen that SPI::beginTransaction was interrupted by an ISR, while it is changing the SPI_AVR_EIMSK register or interruptSave variable (it seems that there is a small window after changing SPI_AVR_EIMSK where an interrupt might still occur). If this happens, interruptSave is overwritten with an invalid value, permanently disabling the pin interrupts. To prevent this, disable interrupts globally while changing these values.

2014-11-25[avr] Improved SPI speed on 16bit transfer.Cristian Maglie
From https://github.com/arduino/Arduino/pull/2376#issuecomment-59671152 Quoting Andrew Kroll: [..this commit..] introduces a small delay that can prevent the wait loop form iterating when running at the maximum speed. This gives you a little more speed, even if it seems counter-intuitive. At lower speeds, it is unnoticed. Watch the output on an oscilloscope when running full SPI speed, and you should see closer back-to-back writes. Quoting Paul Stoffregen: I did quite a bit of experimenting with the NOP addition. The one that's in my copy gives about a 10% speedup on AVR.
