MB90246A Series
7. Simple I/O Serial Interface
The 8/16-bit simple I/O serial interface transfers data synchronously with a clock.
Communications direction: Concurrent processing of transmission (Whether data is to be sent or received
must be judged by the user.)
Transfer mode: Clock synchronization function (Only data are transferred.)
Transfer rate:DC to
φ
/2 (
φ
: Machine clock. Frequencies of up to 8 MHz are available when the machine clock
is rated at 16 MHz.)
Shift clock: A machine clock division clock is used as the shift clock. (One of four division ratios can be
selected.). A shift clock is output only during data transfer.
Data transfer format: MSB first can be selected. 8 or 16 bits can be selected as data length. Only data are
transferred.
Interrupt request: An interrupt request is issued upon termination of transfer.
Inter-CPU connection: Only 1:1 (bidirectional communication)
