… Event detection indicator for SLIC2 (Read-only bit)
… Thermal Shutdown Alarm indicator for SLIC2 (Read-only bit)
By reading the state of this bit, the input level to the DET2 pin can be determined.
If this bit is cleared, the DET2 pin is a logic “0”. If this bit is set, the DET2 pin is a logic
“1”.
When the SLIC connected to channel 2 is an Intersil RSLIC
event of off-hook, ring trip or ground key can be detected by connecting the DET2 pin of
the ML7033 directly to the corresponding output pin of the SLIC device.
The event detected by the the SLIC is determined by the F2_2, F1_2, F0_2 (CR13-B7 to
B5), and E0_2 (CR13-B2) bits.
When a debounce timer is enabled by a setting with the DET2TIM3 through DET2TIM0
bits (CR4-B7 to B4), the DET2 (CR13-B1) bit is held unchanged for a set period, even
when the DET2 pin changes from a logic “1” to a logic “0”.
By reading the state of this bit, the input level to the ALM2 pin can be determined.
If this bit is cleared, the ALM2 pin is a logic “0”. If this bit is set, the ALM2 pin is a logic
“1”.
When the SLIC connected to channel 2 is an Intersil RSLIC
ALM2 pin directly to the corresponding output pin of the SLIC device allows the ML7033
to know whether the SLIC is in the normal operating mode, or in a thermal shutdown state.
