PDVE

These registers are used to monitor pulse density violations when the T1 format

is enabled.

PDVE:

The PDVE bit enables an interrupt to be generated on the INTB pin when a

change in the pulse density is detected. When PDVE is set to logic 1, an

interrupt is generated whenever a pulse density violation occurs or when the

pulse density ceases to exist. When PDVE is set to logic 0, interrupt

generation by pulse density violations is disabled.

Z16DE:

The Z16DE bit enables an interrupt to be generated on the INTB pin when

16 consecutive zeros are detected. When Z16DE is set to logic 1, interrupt is

generation is enabled. When Z16DE is set to logic 0, interrupt generation is

disabled.

PDVI, Z16DI:

The PDVI and Z16DI bits identify the source of a generated interrupt. PDVI is

a logic 1 whenever a change in the pulse density violation state occurs. PDVI

is cleared to 0 when this register is read. Z16DI is a logic 1 whenever 16

consecutive zeros are detected. Z16DI is cleared to 0 when this register is

read.

PDV:

The PDV bit indicates the current state of the pulse density violation detector.

When PDV is a logic 1, a violation of the pulse density rule has been
