Serial I/O2
The serial I/O2 function can be used only for clock synchronous se-
rial I/O.
For clock synchronous serial I/O2 the transmitter and the receiver
must use the same clock. When the internal clock is used, transfer is
started by a write signal to the serial I/O2 register.
[Serial I/O2 control register] SIO2CON
The serial I/O2 control register contains 8 bits which control various
serial I/O functions.
For receiving, set “0” to bit 3.
When receiving, bit 7 is cleared by writing dummy data to serial I/
O2 register after shift is completed.
Bit 7 is set earlier a half cycle of shift clock than completion of shift
operation. Accordingly, when checking shift completion by using
this bit, the setting is as follows:
(1) check that this bit is set to “1”,
(2) wait a half cycle of shift clock,
(3) read/write to serial I/O2 register.
