Because the internal bus for the SH7709S on-chip peripheral modules is 16 bits wide, a time lag
can occur between the time when the upper 16 bits and lower 16 bits are read. Since TCNT counts
sequentially, this time lag can create discrepancies between the data in the upper and lower halves.
To correct the discrepancy, a buffer register is connected to TCNT so that the upper and lower
halves are not read separately. The entire 32-bit data in TCNT can thus be read at once.
TCNT is initialized to H'FFFFFFFF by a power-on reset or manual reset, but is not initialized, and
retains its contents, in standby mode.
