3. I/O Expansion Serial Interface
This block consists of an 8-bit serial I/O interface that can perform clock synchronous data transfer. Either LSB-
first or MSB-first data transfer can be selected.
The following two serial I/O operation modes are available.
Internal shift clock mode: Data transfer is synchronized with the internal clock.
External shift clock mode: Data transfer is synchronized with the clock input from the external pin (SCK). By
manipulating the general-purpose port that shares the external pin (SCK), this
mode also enables the data transfer operation to be driven by CPU instructions.

(2) Register Details
Serial Mode Control Status Register (SMCS)
*1: Only “0” can be written.
*2: Only “1” can be written. Reading always returns “0”.
This register controls the transfer operation mode of the serial I/O. The following describes the function of each
bit.
(a) [bit 3] Serial mode selection bit (MODE)
This bit selects the conditions for starting operation from the halted state. Changing the mode during operation
is prohibited.
The bit is initialized to “0” by a reset. The bit is readable and writable. Set to “1” when using the intelligent I/O
service.
MODE
Operation
0
Start when STRT is set to “1”. [Initial value]
1
Start on reading from or writing to the serial data register.
