#define AVR32_CLEAR_SR_BIT (  sregister,
bitname   ) 
 

Value:

volatile long avr32_sr_clear_value; \
    avr32_sr_clear_value = __builtin_mfsr(sregister); \
    avr32_sr_clear_value &= ~bitname; \

Define which clears a bit in system registers.

Parameters:
sregister address of the system register to modify
bitname offset to the bit which is to be cleared
