Global Register Structure
Global Control Register (GREG4)
This register selects the source of the output second pulse (bit 0—bit 2), interrupt 3-state control (bit 4), and inter-
rupt polarity (bit 6).
Table 64. Global Control Register (GREG4) (004)
Device ID and Version Registers (GREG5—GREG7)
These bits define the device and version number of this framer circuit.

SECOND pin:
Reserved.
INTERRUPT 3-State Control. This bit along with bit 6 in this register (polarity control)
allows the interrupt pin to be programmed for active HIGH, active LOW, wire-OR, or wire-
AND operation, as described below:
Reserved.
Interrupt Polarity Control. A 1 inverts the polarity of the interrupt pin (negative polarity).

Bit 7
Programs the interrupt pin to be active HIGH (1-state) when there is an inter-
rupt condition and to be inactive LOW (0-state) when the condition goes away.
Programs the interrupt pin to be active LOW (0-state) when there is an inter-
rupt condition and to be inactive HIGH (1-state) when the condition goes
away.
Programs the interrupt pin to be active HIGH (1-state) when there is an inter-
rupt condition and to be inactive HIGH-Z (3-state) when the condition goes
away.
Programs the interrupt pin to be active LOW (0-state) when there is an inter-
rupt condition and to be inactive HIGH-Z (3-state) when the condition goes
away.
