Notes 1: As for CAP0, CAP1, it is the value when noise filter is not used.
2: In this time, bit 6 of the serial I/O1 control register (address 001A16) is set to “1” (clock synchronous serial I/O is selected).
When bit 6 of the serial I/O1 control register is “0” (clock asynchronous serial I/O is selected), the rating values are divided by 4.
In this time, bit 6 of the serial I/O2 control register (address 003016) is set to “1” (clock synchronous serial I/O is selected).
When bit 6 of the serial I/O2 control register is “0” (clock asynchronous serial I/O is selected), the rating values are divided by 4.
