Data Transfer Formats
There are four data transfer formats. When the multiprocessor format is specified, the parity bit
specification is invalid. For details, see table 15.10.
Clock
See the description under Clock in section 15.3.2, Operation in Asynchronous Mode.
Data Transfer Operations
Multiprocessor Serial Data Transmission: Figure 15.13 shows a sample flowchart for
multiprocessor serial data transmission.
Use the following procedure for multiprocessor serial data transmission after enabling the SCI for
transmission.
