Description

7-0

LOW_LIMIT. The low limit value to which the associated voltage input data is compared. If the voltage input data

is lower than LOW_LIMIT, the corresponding bits in the HM Interrupt Status register, HM Sensor Status Register

and Status Register are updated/set (see Section 8.4.4 on page 143, Section 8.4.8 on page 147, and

Section 8.5.23 on page 164).
