39.6.3 Output Masking Period

As soon as the analog comparator settings change, the output is invalid for a duration. A masking period is automatically triggered as soon as a write access is performed on the ACC_MR and ACC_CR regardless of the register data content.

The mask period is 8 × t_{peripheral clock} if ACC_ACR.MSEL = 0.

The mask period is 128 × t_{peripheral clock} if ACC_ACR.MSEL = 1.

The masking period is reported by reading a negative value (MASK=’1’) on the ACC Interrupt Status register (ACC_ISR).
