SERIAL INTERFACE
The
μ
PD75216A serial interface has the following functions.
Clock synchronous 8-bit send/receive operation (simultaneous send/receive)
Clock synchronous 8-bit serial bus operation (data input/output from the SO pin. N-ch open-drain SO output)
Start LSB/MSB switching
The above functions facilitates data communication with another microcomputer of
μ
PD7500 series and 78K
series via serial bus and coupling with peripheral devices.
