Functions
•8-bit I/O port with the same function as port P0.
<Input level>
P40, P41 : CMOS input level
P42–P46 : CMOS compatible input level or TTL in-
put level
P47 : CMOS compatible input level or TTL input
level in the bus interface function
<Output structure>
P40, P41, P47 : CMOS 3-state output structure
P42–P46 : CMOS 3-state output structure or N-
channel open-drain output structure
•Regardless of input or output port, P42 to P46 can
be input every pin level.
•When P42 and P43 are used as output port, the
function which makes P42 and P43 clear to “0”
when the host CPU reads the output data bus
buffer 0 can be added.
•8-bit I/O port with the same function as port P0.
•CMOS compatible input level.
•CMOS 3-state output structure.
•P50 to P53 can be switched between CMOS com-
patible input level or TTL input level in the bus
interface function.

The 3886 group is the 8-bit microcomputer based on the 740 family core technology.
The 3886 group is designed for controlling systems that require analog signal processing and include two serial I/O functions, A-D converters, D-A converters, system data bus interface function, watchdog timer, and comparator circuit. The multi-master I2C bus interface can be added by option.
