REN—SMC Receive Enable
7.11.14.5 SMC MONITOR CHANNEL RX BD. The CP reports information about the moni-
tor channel receive byte using this BD.
E—Empty
L—Last (EOM)
ER—Error Condition
MS—Data Mismatch
Bits 11–10—Reserved
DATA—Data Field

When the SMC implements the monitor channel protocol, the SMC will wait until this bit
is set by the CPU32+ core before acknowledging the monitor channel data. In the trans-
parent mode, additional received data bytes will be discarded until the E-bit is set by the
CPU32+ core.
This bit is valid only when the SMC implements the monitor channel protocol. This bit is
set when the end-of-message (EOM) indication is received on the E-bit.
This bit is valid only when the SMC implements the monitor channel protocol. This bit is
set when an error condition occurs on the monitor channel protocol. (A new byte is trans-
mitted before the SMC acknowledges the previous byte.)
This bit is valid only when the SMC implements the monitor channel protocol. This bit is
set when two different consecutive bytes are received and is cleared when the last two
consecutive bytes match. The SMC waits for the reception of two identical consecutive
bytes before writing new data to the Rx BD.
These bits should be cleared by the user.
The data field contains the monitor channel data byte received by the SMC.
