Section 16 Serial I/O with FIFO (SIOF)
16.4 Operation
16.4.1 Serial Clocks
Master/Slave Modes: The following two 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 16.2 shows connections for supply of the serial clock.
