Fig. 10 Structure of serial I/O mode register
Serial I/O common transmission/reception mode.
Write 1 to bit 6 of serial I/O mode register, and signals S
IN
and S
OUT
switch internal to be able to serial data transmission/reception.
Figure 11 shows signals on serial I/O common transmission/recep-
tion mode.
Note :
Receive the serial data after writing “FF

” to the serial I/O
register.
