15.4.1
Master/Slave Modes: The following 2 modes are available as the SIOF clock mode.
• Slave mode: SIOFSCK, SIOFSYNC input
• Master mode: SIOFSCK, SIOFSYNC output
Baud Rate Generator: In SIOF master mode, the baud rate generator (BRG) is used to generate
the serial clock. The division ratio is from 1/1 to 1/1024.
Figure 15.2 shows connections for supply of the serial clock.
Table 15.3 shows an example of serial clock frequency.
