1 = Change in V
0 = No interrupt on V
See register 0x00, B6.
1 = Transition in CKILL bit from 0 to 1 triggers a hard-
0 = No interrupt on CKILL changes (default).
See register 0x00, B4.
1 = Change in ADCOVR bit from 0 to 1 triggers a
0 = No interrupt on ADCOVR changes (default).
See register 0x00, B3.
1 = Change in L525 bit status triggers a hardware
0 = No interrupt on L525 changes (default).
This interrupt is masked by the HLOCK and LSTLCK
status. Changes in the L525 status triggers a hardware
interrupt only when HLOCK = 1 and LSTLCK = 0. See
register 0x01, B6.
