+/**
+ * @brief	ChibiOS has a nasty bug in its _adc_isr_full_code() routine (defined in adc.h as a macro).
+ * 			Do we have the version of ChibiOS with this bug.
+ * @detail	Set to TRUE if ChibiOS has this bug.
+ * @note	Fixed in ChibiOS 2.4.4stable and 2.5.2unstable (and the repository from 18th Feb 2013)
+ * @note	This bug prevents us re-calling adcStartConversionI() from with the ISR even though
+ * 			it is clearly designed to handle it. For some reason (on this micro) the high speed timer
+ * 			is not affected only the single sample low speed timer. In that situation we wait until
+ * 			we get back to thread land. This is terrible for the accuracy of the high speed timer
+ * 			but what can we do (other than fix the bug).
+ * @note	For the AT91SAM7 ADC driver, it post-dates the finding of the bug so we safely
+ * 			say that the bug doesn't exist for this driver.
