(1-2) 9 bit transfer mode
Set ICKS on bit 3 of control register 1 to high. Since low is the initial value at reset, 8 bit data
transfer can be performed until ICKS is set to high. The unit of transfer is 9 bit, an 8 bit data plus
1 bit for ODD parity. If the result of the parity check is NG, the TC9332F does not fetch the set
data, so always be sure to input the correct parity. Figure 10 (a) shows an example of timing for
the 8 bit transfer mode.

Data bus (DBUS) data output format
At idle, the CS , IFCD, IFCK and IFDI signals are "H" level.
There are two transfer modes that can be used, depending on the length of data to be transferred.
Figure 11 shows examples of timing for the 8 bit and 9 bit transfer modes.
The data transmitted from the microcontroller is a 1 byte command word.
The data output to the microcontroller are the 24 bit on the internal DBUS or the upper 16 bit, and
are sent LSB first.
