In variable data length clock synchronous mode, full-duplex clock synchronous serial communication is
allowed. Transmit data can be selected from 1 to 8 bits long. Continuous transmit/receive operations enable to
communicate more than 9 bit-long data. Table 22.25 lists specifications of the group 2 variable data length
clock synchronous mode. Table 22.26 lists register settings. Table 22.27 lists pin settings. Figure 22.61 shows
an example of a transmit and receive operation.

The G2PO0 register determines a baud rate and the serial clock is generated in
phase-delayed waveform output mode of the channel 2.
The serial clock is input from the ISCLK2 pin.
