… Event detection indicator for SLIC2 (Read-only bit)

0 : detected

1 : not detected

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

TM series device, an assigned

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”.

… Thermal Shutdown Alarm indicator for SLIC2 (Read-only bit)

0 : detect

1 : not

detect

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

TM series device, connecting the

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.
