From: lottaviano Date: Sat, 9 Apr 2011 13:41:54 +0000 (+0000) Subject: Add detect macros for AVR XMega MCU. X-Git-Tag: 2.7.0~123 X-Git-Url: https://codewiz.org/gitweb?a=commitdiff_plain;h=2e1423c0e63c12bb4eb996480ec2a51f8899aa88;p=bertos.git Add detect macros for AVR XMega MCU. Hardware interrupts should be enabled separately by using the lines: #include PMIC.CTRL |= PMIC_LOLVLEX_bm | PMIC_MEDLVLEX_bm | PMIC_HILVLEX_bm; These should go into a separate init file specific for AVR XMega.
