16.2 The method of Serial I/O
1. Select transmission/receiving mode.
2. In case of sending mode, write data to be send to SIOR.
3. Set SIOST to “1” to start serial transmission.
4. The SIO interrupt is generated at the completion of SIO
and SIOIF is set to “1”. In SIO interrupt service routine,
correct transmission should be tested.
5. In case of receiving mode, the received data is acquired
by reading the SIOR.
Note:
When external clock is used, the frequency should
be less than 1MHz and recommended duty is 50%. If both
transmission mode is selected and transmission is per-
formed simultaneously, error will be made.
