7—0 DMD[7:0] Downstream Monitor Data. For any multibyte monitor message, all message bytes except
the last one are written to this register for transmission on the downstream monitor channel
(see Section 10.3.2, Monitor Message Transfer). The DMRDY interrupt bit provides an indica-
tion that a new byte may be loaded.

register for transmission on downstream monitor channel (see Section 10.3.2, Monitor Mes-
sage Transfer). The DMRDY interrupt bit provides an indication that a new byte may be
loaded.

Upstream Monitor Channel Received Data. The most recent successfully received byte
of an upstream monitor message is made available in this register (see Section 10.3.2,
Monitor Message Transfer). The UMRDY interrupt bit provides an indication that a new
byte has been received.
