Notes 1.
Circled characters indicate the Schmitt-trigger input.
BP0 through BP7 select V
LC1
as an input source.
However, the output levels change depending on the external circuit of BP0 through BP7 and V
LC1
.
2.
Example
Because BP0 through BP7 are mutually connected inside the
μ
PD753036, the output levels
of BP0 through BP7 are determined by R
1
, R
2
, and R
3
.
Programmable 4-bit input/output port
(PORT6).
This port can be specified for input/output
bit-wise.
Connections of on-chip pull-up resistors
can be specified by software in 4-bit units.
4-bit input/output port (PORT7).
Connections of on-chip pull-up resistors
can be specified by software in 4-bit units.
4-bit input/output port (PORT8).
Connections of on-chip pull-up resistors
can be specified by software in 4-bit units.
1-bit output port (BIT PORT)
Also used for segment output pins.
