The following modes are available as the SIOF clock mode.
• Slave mode: SIOF_SCK, SIOF_SYNC input
• Master mode: SIOF_SCK, SIOF_SYNC output
(2)
In SIOF master mode, the baud rate generator (BRG) is used to generate the serial clock. The baud
rate generator consists of the prescaler that can select 32 types of division ratio from 1 to 1/32 with
the BRPS4 to BRPS0 bits in SISCR and divider that can select the division ratio from 1, 1/2, 1/4,
1/8, 1/16, and 1/32, with the BRDV2 to BRDV0 bits in SISCR. The division ratio of the baud rate
generator ranges from 1 to 1/1024 of the product of the division ratios of the prescaler and the
divider.
When the master clock is not divided by the baud rate generator (the division ratio is 1), set the
MSIMM bit in SISCR to 1 and use the master clock without division as a serial clock.
Figure 29.2 shows connections for supply of the serial clock.
Table 29.5 shows an example of serial clock frequency.
