DIGA Communications Test registers are used by diagnostic self-
test code only.

The Console Communications registers are implemented in DIGA0. The
same registers exist in DIGA1,2,3. To facilitate individual loads of
DIGA1,2,3, the Console Communications registers are used as scratchpad
areas. Each CPU is allocated its own pair of registers. A write to TL-
CON00 updates TLCON00, 0A, 0B, and 0C. A write to TLCON10 updates
TLCON10, 1A, 1B, and 1C. A read of any of these registers returns the
value stored in it. Writes targeted at 0A, 0B, 0C, 1A, 1B, or 1C are han-
dled as writes to nonexistent CSRs.
