pulses supplied from Flashpro III during initialization of serial
communication. The pin used for the communication is decided depending on this number.
2. Select from 9,600 bps, 19,200 bps, 38,400 bps, or 76,800 bps.
Remark COMM PORT : Selection of serial port.
SIO CLK : Selection of serial clock frequency.
CPU CLK : Selection of source of CPU clock to be input.
