Port C is an 4-bit bi-directional programmable Input / Output port with
6
I/O Pull-high or Open-drain option. As inputs, Port C can be in either
5
I/O the Pure or Pull-high states. As outputs Port C can be a Buffer or
4
I/O Open-drain NMOS type (sink current).

I/O IOC1:EXT INT IN
IOC2:EXT COUNT IN
**See note 1 and 2 below.
Port D is an 6-bit bi-directional programmable Input / Output port with
17
I/O Pull-low or Open-drain option. As inputs, Port D can be either Pure
16
I/O or Pull-low states. As outputs, Port D can be either Buffer or Open-
15
I/O drain PMOS type (send current).

* Refer to SPC Programming Guide for complete information.
**Note: 1.) Two input states can be specified; Pure Input, Pull-High or Pull Low.
2.) Three output states can be specified as Buffer output, Open Drain PMOS output (send), or Open
Drain NMOS output (sink).
