Section 20 Serial IO (SIOF)
20.3
20.3.1
(1) Master/Slave
There are two modes as serial clock listed as below.
• Slave mode: SCK_SIO and SIOFSYNC is input.
• Master mode: SCK_SIO and SIOFSYNC is output.
(2) Baud Rate Generator (BRG)
At the SIOF master mode, serial clock is generated using the baud rate generator (BRG). The baud
rate can be selected from 1/2 to 1/1024.
Figure 20.2 shows the serial clock supply system.
Table 20.3 shows examples about serial clock frequency.
