ACMMOD (ACM Mode Control). Configures the operation mode of the ACM module. See “ACM Operating
Sequences” on page 211. This value becomes the active mode after writing a 1 to START bit in ACMCTS
register.

INTEMEN (Interrupt from End-of-Measurement Event Enable). Enables generation of an ACM interrupt on an
End of Voltage Measurement Burst event (EOMEV in ACMCTS register).
0: Disabled (default)
1: Enabled - ACM Interrupt from EOMEV
INTOUEN (Interrupt from Over/Under Threshold Event Enable). Enables generation of an ACM interrupt on
at least one input above (or below) the threshold event (OVUNTHEV ACMCTS register).

1: Enabled - ACM Interrupt from OVUNTHEV
OVUNSEL (Over or Under Threshold Select). “Any Over” or “Any Under” logic selection for OVUNTHEV bit in
ACMCTS register.
0: At least one input below threshold sets OVUNTHEV=1 (default)
1: At least one input above threshold sets OVUNTHEV=1
Reserved.
Description
ACM disabled (default)
Voltage Level Burst mode - single measurement of the voltage level for all the eight inputs
Threshold Comparison Burst mode - single comparison of all the eight inputs to the set threshold
Low-Power Threshold Comparison mode - periodic comparison of the inputs to a constant threshold
(recommended for Idle PC87591x operation mode). Its operation is stopped by the
selection of a different mode (ACM disabled = 002 is the recommended value).
