I/O Ports
The NT6868A has 31 pins dedicated to input and output. These pins are grouped into 6 ports, as follows:
PORT 0 (P00 - P07):
Port 0 is an 8-bit bi-directional CMOS I/O port that is internally pulled High by PMOS. Each pin of port 0 can be bit
programmed as an input or output pin under the software control. When programmed as output, data is latched to the port
data register and output to the pin. Port 0 pins with ''1'' written to them are pulled high by the internal PMOS pull-ups, and
are used as inputs in that state. These input signals can then be read. The port output is High after reset.
PORT 1 ( P10 - P17 ) : Functions the same as PORT 0.
PORT 2 ( P20 - P27) : Functions the same as PORT 0.
PORT 3 ( P30 - P34) : Functions the same as PORT 0.
CLK & DATA
: These two pins have the same structure as I/O ports, except for the 10K
internal pull-ups.
