ICMP_INT
The ICMP_INT bit is set to a logic one when the ICMP input is sampled by the SBSLITE. In
TelecomBus mode, ICMP is sampled during the first C1 position of every frame, as marked
by IC1FP. In SBI mode, ICMP is sampled during the first C1 position of every 4 or 48 frame
multiframe, as marked by IC1FP. This interrupt may be helpful in scheduling configuration
page changes in the IMSU. This interrupt is enabled with the ICMPE bit in the SBSLITE
Interrupt Enable register. This interrupt bit will be cleared when read.
OCMP_INT
The OCMP_INT bit is set to a logic one when the OCMP input is sampled by the SBSLITE.
In TelecomBus mode, OCMP is sampled during the first C1 position of every frame, as
marked by RC1FP. In SBI mode, OCMP is sampled during the first C1 position of every 4 or
48 frame multiframe, as marked by RC1FP. This interrupt may be helpful in scheduling
configuration page changes in the OMSU. This interrupt is enabled with the OCMPE bit in
the SBSLITE Interrupt Enable register. This interrupt bit will be cleared when read.
Reserved
The Reserved bits should be ignored when this register is read.
