A Side Drop Bus Channel n J2 and N2 Byte Message Segments: The
following locations store the A side drop bus 64-byte J2 message when
control bit AnJ2S1 is a 1, and 16-byte J2 and N2 drop and microprocessor
written comparison messages when control bit ARnJ2S1 is a 0. The follow-
ing list the location of the drop message segments and the microprocessor
written segments.

A Side Drop Bus Channel n V1 Byte: This register is updated every 500
microseconds. This location stores the A side drop bus V1 byte pointer byte
for the VT/TU selected. Bit 7 in this register corresponds to bit 1 in the V1
byte.
A Side Drop Bus Channel n V2 Byte: This register is updated every 500
microseconds. This location stores the A side drop bus V2 byte pointer byte
for the VT/TU selected. Bit 7 in this register corresponds to bit 1 in the V2
byte.
A Side Drop Bus Channel n V4 Byte: This register is updated every 500
microseconds. This location stores the A side drop bus V4 byte for the
VT/TU selected. Bit 7 in this register corresponds to bit 1 in the V4 byte.
A Side Drop Bus Channel n V5 Overhead Byte: This register is updated
every 500 microseconds. This location stores the A side drop bus V5 over-
head byte for the VT/TU selected. Bit 7 in this register corresponds to bit 1
in the V5 byte.
A Side Drop Bus Channel n J2 Overhead Byte: This register is updated
every 500 microseconds. This location stores the A side drop bus J2 over-
head J2 byte for the VT/TU selected. Bit 7 in this register corresponds to bit
1 in the V5 byte.
A Side Drop Bus Channel n N2 Overhead Byte: This register is updated
every 500 microseconds. This location stores the A side drop bus N2 over-
head byte for the VT/TU selected. Bit 7 in this register corresponds to bit 1
in the N2 byte.
A Side Drop Bus Channel n K4 Overhead Byte: This register is updated
every 500 microseconds. This location stores the A side drop bus K4 over-
head byte for the VT/TU selected. Bit 7 in this register corresponds to bit 1
in the K4 byte.
