Serial Management Controllers (SMCs)
7.11.5.4 SMC RECEIVER SHORTCUT SEQUENCE. A shorter sequence is possible if the
user desires to reinitialize the receive parameters to the state they had after reset. This se-
quence is as follows:
7.11.5.5 SWITCHING PROTOCOLS. Sometimes the user desires to switch the protocol
that the SMC is executing (for instance, UART to Transparent) without resetting the board
or affecting any other SMC. This can be accomplished using only one command and a short
number of steps:
7.11.6 Saving Power
When the TEN and REN bits of an SMC are cleared, that SMC consumes a minimal amount
of power.
7.11.7 SMC as a UART
The following paragraphs describe the use of the SMC as a UART.
7.11.7.1 SMC UART KEY FEATURES. The SMC UART contains the following key fea-
tures:
7.11.7.2 SMC UART COMPARISON. As compared to the UART modes supported by the
SCCs, the SMCs generally offer less functionality and performance. This fits with their pur-
pose of providing simple debug/monitor ports rather than full-featured UARTs. The SMC
UARTs do not support the following features:

1. Clear the REN bit in the SMCMR.
2. INIT RX PARAMETERS command. Any additional modifications may now be made.
3. Set the REN bit in the SMCMR.
1. Clear the TEN and REN bits in the SMCMR.
2. INIT TX AND RX PARAMETERS command. This one command initializes both trans-
3. Set the SMCMR TEN and REN bits. The SMC is enabled with the new protocol.
