・ fc = 9.8304MHz
・ fgear = 9.8304MHz (CGSYSCR<GEAR[2:0]> = "000" : fc selected)
・ ΦT0 = 4.9152MHz (CGSYSCR<PRCK[2:0]> = "001" : 2 division ratio)
The highest baud rate is less than 40 ÷ 8 = 5.0 Mbps.
The highest baud rate is 1.25Mbps because 20MHz is divided by 16.
Table 10-8 shows examples of baud rate when the baud rate generator is used with the
To use SCLK input, the following conditions must be satisfied.
- SCLK cycle > 2/fsys
The highest baud rate must be less than 40 ÷ 2 ÷ 16 = 1.25 Mbps.
Since the highest value of fsys is 40MHz, the highest baud rate is 40 ÷ 16 = 2.5Mbps.
