10. SERIAL INTERFACE I/O
The SPC122A provides serial interface I/O mode for extending size
of ROM/RAM. Serial Interface I/O Port can be used to read/write
data from/to extra memory.
control register for programming interface I/O.
11. SPEECH AND MELODY
For speech synthesis, the SPC122A can provide NMI for precise
sampling frequency. Users can record or synthesize the sound
and store it into ROM.
