… Event detection indicator for SLIC1 (Read-only bit)
… Thermal Shutdown Alarm indicator for SLIC1 (Read-only bit)
By reading the state of this bit, the input level to the DET1 pin can be known. If this bit is
cleared it indicates that the DET1 pin is in the logic “0” state. If this bit is set it indicates
that the DET1 pin is in the logic “1” state.
When the SLIC connected to channel 1 is from the Intersil RSLIC
can be connected directly to the corresponding output pin of the SLIC device. This allows
an assigned event such as off-hook, ring trip, or ground key to be detected. The event
detected by the SLIC detects is determined by the F2_1, F1_1, F0_1 (CR6-B7 to B5), and
E0_1 (CR6-B2) bits.
When the debounce timer is enabled by setting the DET1TIM3 through DET1TIM0 bits
(CR4-B3 to B0), the DET1 (CR6-B1) bit is held unchanged for a set period, even when the
DET1 input pin changes from logic “1” to logic “0”.
By reading this bit, the input level to the ALM1 pin can be known. When this bit is cleared,
the ALM1 pin is a logic “0”. When this bit is set, the pin is a logic “1”.
When the SLIC connected to channel 1 is from the Intersil RSLIC
can be connected directly to the corresponding output pin of the SLIC device. This allows
the user to know whether the SLIC1 is in the normal operating state, or in the thermal
shutdown state.
