7.11.7.12 SMC UART RECEIVE BUFFER DESCRIPTOR (RX BD). •The CP reports infor-
An example of the UART Rx BD process is shown in Figure 7-76. This figure shows the
resulting state of the Rx BDs after receipt of 10 characters, an idle period, and five charac-
ters—one with a framing error. The example assumes that MRBLR = 8 in the SMC param-
eter RAM.
E—Empty
Bits 14, 11, 10, 7, 6, 2—Reserved
MOTOROLA
1. Detection of an error during message processing
2. Detection of a full receive buffer
3. Reception of a programmable number of consecutive idle characters

mation concerning the received data on a per-buffer basis via Rx BDs. The CP closes
the current buffer, generates a maskable interrupt, and starts to receive data into the
next buffer after one of the following events:
0 = The data buffer associated with this Rx BD has been filled with received data, or
1 = The data buffer associated with this BD is empty, or reception is currently in
data reception has been aborted due to an error condition. The CPU32+ core is
free to examine or write to any fields of this Rx BD. The CP will not use this BD
again while the E-bit remains zero.
progress. This Rx BD and its associated receive buffer are owned by the CP. Once
the E-bit is set, the CPU32+ core should not write any fields of this Rx BD.
