DPME:
The DPME bit controls the generation of an interrupt on the microprocessor
INTB pin by the driver performance monitor portion of XPLS. When DPME is
set to logic 1, an interrupt is generated on INTB whenever an alarm condition
occurs on the driver performance monitor points. A driver performance
monitor alarm is declared whenever a period of 62 or 63 consecutive bit
periods with no pulses on either the TXTIP[x] or TXRING[x] output pins
occurs. The exact threshold (62 or 63 bit periods) depends on the line build-
out and the pattern of bipolar violations. When DPME is set to logic 0,
detection of a driver performance monitor alarm condition is disabled from
generating an interrupt.
