Notes 1.
Circled characters indicate the Schmitt-trigger input.
For BP0 to BP7, V
LC1
is selected as an input source.
The output levels differ depending on BP0 to BP7 and the external circuit of the V
LC1
.
2.
Example
BP0 to BP7 are connected each other internally in the
μ
PD753017 as shown below. Therefore, the
output levels of BP0 to BP7 are determined by the levels of R

, and R

Programmable 4-bit input/output port
(PORT6).
This port can be specified for input/output
bit-wise.
On-chip pull-up resistors can be specified
in software in 4-bit units.
4-bit input/output port (PORT7).
On-chip pull-up resistors can be specified
in software in 4-bit units.
1-bit output port (BIT PORT)
Also used for segment output pins.
