The SMCs in UART mode, however, do provide one feature not provided by the regular
SCCs. The SMCs allow a data length option of up to 14 bits; whereas, the SCCs provide a
data length up to 8 bits. See Figure 7-75 for the SMC UART frame format.
7.11.7.3 SMC UART MEMORY MAP. When configured to operate in UART mode, the
QUICC overlays the structure listed in Table 7-5 with the UART-specific parameters
described in Table 7-13.
MAX_IDL. Once a character of data is received on the line, the UART controller begins
counting any idle characters received. If a MAX_IDL number of idle characters is received
before the next data character is received, an idle timeout occurs, and the buffer is closed.
This, in turn, can produce an interrupt request to the CPU32+ core to receive the data from
• Fractional Stop Bits
• Built-In Multidrop Modes
• Freeze Mode for Implementing Flow Control
• Isochronous Operation (1x Clock)
• Interrupts upon Receiving Special Control Characters
• Ability To Transmit Data on Demand using the TODR
• SCCS Register To Determine Idle Status of the Receive Pin
• Other Features for the SCCs as Described in the GSMR
