Serial I/O
qSerial I/O1
Serial I/O1 is used as the clock synchronous serial I/O and has an
ordinary mode and an automatic transfer mode. In the automatic
transfer mode, serial transfer is performed through the serial I/O
automatic transfer RAM which has up to 256 bytes (addresses
0F0016 to 0FFF16: addresses 0F6016 to 0FFF16 are also used as
Fig. 19 Block Diagram of Serial I/O1
FLD automatic display RAM).
________
The P62/SRDY1/AN8, P64/INT4/SBUSY1/AN10, and P65/SSTB1/AN11
pins each have a handshake I/O signal function and can select
either “H” active or “L” active for active logic.
